The area that Peggy and Jarvis found themselves in was pitch black. Quickly they flared out their wrist lights.

The bright beams revealed amazing scenery. The smashed interior was like nothing they had ever seen before. Colorful fish swam around, and even a small octopus was hiding under a rocky outcrop. It seemed that parts of the disheveled area had been converted into homes for many different aquatic life. And where there was a space, spikey barnacles were attached. It was a beautiful natural aquarium, and they marveled at its simplicity.

Howard's breathless, "Wow, that sure is stunning," broke through their awe.

Grinning, the pair then aimed their lights past this vibrant array of adaptive nature.

Swinging them around highlighted the damage done due to the structure's hard landing and all the centuries of being submerged. Among the destruction, a long marble staircase had been tossed about from the impact. Also, a collapsed circular ramp was piled on top of each other.

They heard Spencer mumble, "That must be the ramp that was used for the oxen to haul the supplies up to the top level." Unfortunately, these massive stone slabs blocked the direct route to the upper tier. They would have to find another way.

After a grim nod to one another, Peggy and Jarvis fanned out. With the Pharos Lighthouse knocked on its side, it took a bit for Peggy to orientate herself, but soon she was easily scrambling about the ruined interior. She was grateful for the rubber-soled booties that Howard had provided.

As they made their way deeper into the unknown, Jarvis found a potential route to take and called Peggy over. She viewed the small opening with trepidation.

Howard cleared his throat, "With everything so jumbled, you could find yourself twisted around or, worse, stuck in a dead-end. But not to worry, I packed a guideline for you just in case."

Removing it from the bag, Peggy tied one end of the bright orange rope around a broken column.

She was about to crawl in when Howard stated, "Now be careful guys, these inner works might not be very stable."

Taking his warning to heart, Peggy cautiously entered. Thankfully there were no problems, and after Jarvis had joined her, they pressed onwards.

Slowly they began to maneuver their way through the slanted and broken mess of corridors. Makeshift passageways went in all directions. Peggy hoped they would eventually reach their final destination if they kept angling north.

But after heading down a shrunken corridor of twists and turns, they ended up in a cul-de-sac. Thankfully, Howard's guide rope helped them retrace their way back to the last junction.

As they took the other route, Jarvis quipped, "I feel like a rat in a maze."

Finally, they came upon a massive slanted stone slab angled to higher ground. They took it in hopes that they had found their way through this topsy-turvy jumbled mess this time.

After climbing up the steep incline, they soon found themselves in a crooked corridor with barely any water underfoot. Before Jarvis could remove his regulator, Peggy stopped him, "It might not be safe to breathe."

Howard added to her warning, "Yeah, I am sure it would be a relief for you, Jarvis, but I'd bet there's more CO2 than oxygen. You better keep your masks on."

Peggy answered, "Affirmative, Howard." As they continued, she vaguely recalled a campfire story that her Howling Commando friend Jim Morita had regaled to them years ago. He said that he had to hide in a cave with underwater caverns while eluding capture from a Hydra search party.

With the enemy closing in, he had no choice but to use them to escape. Resting in one of the many networks of underground grottos, he realized that the CO2 levels were rising with every breath he took. Obviously, he had lived but replied that he would never forget the feeling of slowly suffocating to death.

Peggy knew that, unlike land-based caves, this one could not replenish on its own. But on the plus side, they were no longer submerged in seawater anymore. She doubted being waterlogged for so long was good for her skin.

Once they contorted through another crooked opening, they entered a vast chamber. Quickly they shone their lights around as they surveyed the large room. Tossed about the mess were old bits of cracked and broken bronze mirrors. And tucked in the back were some large animal pens.

They heard Professor Spencer surmise excitedly, "Due to the contents and the size of the room, I believe you have finally made it to the upper-tiered supply chamber."

Jarvis and Peggy shared a relieved smile.

Howard's voice chirped, "As you look around, don't forget to keep an eye out for that specialized fuel source."

"Of course, Howard," Peggy chimed back. Then after a quick exhale of determination, they began investigating the room.

Though the interior was a wreck, it was still in better shape than the middle section had been. This gave a lot of credence to what Howard had said about the top tier being the most fortified section of the Lighthouse.

Besides the broken bronze pieces of mirrors, they found decayed strands of wetlands strewn about the floor. Jarvis lightly kicked a bale of something that resembled dirty wheat. "Do you think we found what they used for the fire? Maybe it is from the grasslands that are near the Nile Delta?"

Peggy eyed the dried-out remnants and wondered aloud, "For such a purported bright light, they must have treated it with something."

Howard concurred, "Yeah, they definitely added something to it to generate such an intense beam."

While Peggy poked about the broken mirrors, Jarvis was investigating the animal pens with the scanner.

"I wonder what animals they kept here," Using his rubber bootie, Jarvis nudged the few wooden slats that would have been part of the collapsed enclosure. It was a large pen that still had pieces of petrified straw miraculously stuck to what had once been the floor.

Spencer interjected, "Oh, that was probably where they housed all those oxen that hoisted up their provisions."

Peggy mused, "How strange. I wonder why they were kept up here and not in the middle section."

Jarvis knocked aside the pen's debris and found a large clump of fossilized animal shat. It seemed to glisten when he aimed his wrist light on it, and the dung sparkled prettily for him. Among bits of possible semi-digested animal bones, the dropping appeared to have minerals in it. Hearing his intrigued murmur, Peggy came over.

Perplexed, she muttered, "That's odd. There are even a couple of piles of it in the corner by the mirrors. I wonder why they didn't get rid of it."

Jarvis asked hopeful, "Are those sparkly bits gold?"

Howard countered, "No, but it sure is funny-looking animal dung. I doubt it is oxen, not with the bone pieces in it."

As he mulled it over, he asked, "Now Peg, you found piles of it near the mirrors, huh? I know that in some cultures, they would use such material as fuel. I wonder if this could be the specialized energy source for the Lighthouse's deadly signal. And if so, it could very well be the most prized poop ever found. Jarvis, you best grab some and bring it back with you so I can run some tests on it."

Jarvis was horrified, "Oh no, Mr. Stark. Now I have done many questionable things for you in the past, but carrying around mummified animal waste will not be tolerated!"

But Howard did not need to wheedle, for Jarvis would do what he was asked.

After exhibiting a sour expression, Jarvis gingerly kicked some free. Then, with disdain, he shoved the piece of the petrified dung into the bag.

Now with that task completed, they continued onwards.

Surprisingly, they came across an immense crater in the ground that had been filled in with rubble. Peggy and Jarvis gave it a curious look, but nothing was interesting about the pit. After circumventing it, they walked to the end of the chamber and through an exit.

They stopped at the threshold and realized they had finally made it to the beacon room.

Jutting over their heads was a massive stand for the mirror. Because the tower was on its side, the entire contraption stuck out of a huge hollow bowl, and only half of a ginormous mirror was still attached.

Shining her flashlight past that, Peggy studied their surroundings in surprise. Recalling that this tier was buried under silt, she figured that with all the multiple large openings for the beacon's light to shine through, their path would have been blocked.

But instead, there was no huge mound of dirt obstructing their way. Looking up, she gasped. Instead, the earth was packed tightly into the exposed windows, sealing them from the sea. It all seemed very unnatural, and she wondered how this could have been possible, especially so far underwater.

Jarvis noticed what she was staring at and targeted the scanner upwards. Both he and Peggy gazed at it in trepidation.

Howard whistled, "That's incredible. The engineering feat alone shows how technically advanced those who set up this treasure hunt were."

"Yes, and this also proves that we must be on the right track," Peggy could not help the sound of relief in her voice. If there had been any doubt regarding this venture, it was now long gone.

"You think it is stable?" Jarvis asked worriedly.

With assurance, Howard stated, "It's held up for centuries, pal. Just don't go poking at it."

Jarvis sniffed, offended and Peggy smirked at their exchange.

Moving forwards, Peggy had to stop abruptly.

At her feet, instead of finding the large opening resting on a sandy floor, a jagged crevice traveled the entire length and beyond. And the area looked weak, almost as if it could collapse at any moment.

She motioned for Jarvis to step back. Behind her, he stared at the dangerous fissure in amazement and concern.

While Jarvis targeted the scanner at it, Peggy cautiously peaked over into the void. Nothing but darkness greeted them from the gap.

Peggy heard Howard's cautioning voice in her ear, "This part of the Lighthouse must have fallen on top of some sort of underwater cave system. The impact is probably what caused the ground to give way. Careful where you step guys. Who knows how stable it is."

True to his warning, a small part of the ledge that Peggy was leaning over tumbled into the crevice, expanding it further. Smartly, Jarvis turned on his heel and headed back to the massive center platform where half of the mirror was still housed.

While he continued to check it out, Peggy surmised out loud, "This must be part of the test. Otherwise, this weakened section would have been shored up just as the storage room's large crater had been."

Howard agreed, "Good call, Peg. I wonder how deep it goes."

Jarvis mumbled from the mirror stand, "Hopefully not to hell."

Being tall enough to see over into the enclosure, Jarvis frowned when he saw bits of dried brown fecal matter stuck to the inside. The material glistened like the night sky when he shone his light on it. With disdain, he supplied, "Unfortunately, Mr. Stark was right about the fuel source being that animal dung. I wonder what makes it glitter like that."

Still staring into the abyss, Peggy quipped, "I'm more concerned about what sort of creature could produce something like that."

Enamored, Howard breathed out, "It would certainly be worth its weight in gold, pal."

Peggy smirked.

"Well, other than the magical dung, I do not see anything that is clue worthy," she replied, resigned. Then shining her light to where the top of the curved dome would have normally been, she saw a giant mosaic that decorated the flat ceiling instead. "Will you look at that," she breathed, intrigued.

After Howard's urging, Jarvis aimed the scanner at the impressive tiled artwork. The entire piece was easily twenty feet in diameter. It depicted the Sea God Poseidon with some creature curled behind him, eating its tail.

Spencer crooned, "Traditionally, the cupola would have been kept open. Instead, it looks like they sealed it off purposely. I bet the clue is behind that."

Howard insisted, "Get closer."

Having already planned on doing so, Peggy carefully walked around the boundary of the dangerous fissure towards the mosaic.

Keeping clear of the unstable crevice, Jarvis followed close behind her.

As they neared, Jarvis muttered, "Is that symbol behind Poseidon an Ouroboros? I thought those were traditionally snakes or dragons. The body doesn't appear like either of them. I wish the creature's face hadn't been bashed in so I could identify what it was supposed to be."

Spencer replied, "The Ouroboros usually signified the cycle of life or renewal. I wonder why that is there."

Peggy saw that the damaged area had a small opening just big enough for a person to fit through.

Crouching by the circular edge of the artwork, she shone the flashlight inside the hole and watched as the beam disappeared. Then, she said, astonished, "I think you are right about the clue being behind this, Professor. It looks like a concealed room is within the sealed cupola."

Howard and Spencer murmured excitedly at her findings.

While Jarvis finished scanning the mosaic, Peggy studied the jagged lip of the entrance. She then shook her head, "And I don't think we were the first ones here either. It's been broken into. See, this isn't natural. Just look at the edges," she ran her hand over the inconsistent breakage and added, "When compared to the other damage that we have seen so far from the fall, this had obviously been bashed in, probably with a hammer."

"Aim the scanner in there and let's make sure that we are alone," Peggy advised, and Jarvis quickly nodded.

He then poked the scanner lens into the hole. After a moment, Howard informed them, "It looks all clear. But there are some deep holes in the ground, and the wall overhead looks to have seen better days."

Spencer's excited voice boomed, startling them, "Yes, hurry, go in there!"

But due to the opening's small size, they would have to leave their larger gear outside. "Howard, we seem to be in a bit of a quandary. We cannot get through with most of our gear."

Proud, Howard boasted, "Not to worry, Peg. Most of the equipment can be adapted in size. For the scanner, you can detach it and leave the bulker transmitter part behind. Just make sure that they are near each other. Here's hoping the thick mosaic walls won't affect the transmission too much."

Impressed, Peggy helped Jarvis do as Howard advised. Once more, she admired her brilliant friend's inventiveness.

Sounding concerned, Howard mentioned, "Hey Peg, looking at how unstable the dome's interior is, I think the compression gun would be too risky to use within it."

Nodding, she did not mind leaving it behind. She preferred the more reliable speargun anyway.

"Now, what about our air tanks? Breathing is a plus," Peggy added with a grin.

She could hear Howard's smile when he replied, "In the bag are smaller breathing tubes. But the oxygen will only last you about 15 minutes. So you best be quick with your investigations."

After Jarvis fished out the smaller oblong tanks, Howard continued with instructions, "Now, carefully unscrew the oxygen regulator from your masks. You should have a couple of extra seconds of air still inside. That's plenty of time to screw in the smaller tanks. And don't worry, I made the masks so that when the sensors register oxygen intake, the valve will automatically open back up."

Peggy snorted. It was Howard's generous way of saying that it was idiot-proof.

So by following his instructions, Peggy and Jarvis took turns helping one another. Thankfully there were no issues, and they successfully changed out the larger air tanks to the mini ones.

Howard added, "Oh, and you better take the bag. It contains the backup battery for the scanner, just in case." Jarvis nodded and secured the almost empty backpack closer to his body so he could fit through.

All set, Peggy carefully nestled the speargun against her side. She wanted to ensure that it would instantly be ready if needed. With the weapons blunted stock tucked under her right arm, she found it a comforting weight.

She then nodded determinedly to Jarvis. "Hopefully, this won't take long."

Praying she would not become stuck, the SSR Agent turned to the side and began to squeeze through. Taking a deep breath did not do much to compress her chest, but she figured it couldn't hurt.

As Peggy pushed in, the suit thankfully protected her skin because she would have surely left some behind on the jagged edges.

Howard cautioned, "Careful Peg. Don't rip the suit, or you might trigger the automatic safety protocols."

"Great, thanks so much for reminding me now," Peggy muttered.

Once all the way through, she cautiously looked above. Peggy noticed that there were many cracks overhead as well as around the way she had just come in. She wondered if the impact from the fall had caused all this damage or if those forcing their way in had.

Jarvis handed her the compact scanner. As he contorted his lanky form through the hole, Peggy surveyed the rest of the chamber. Even with the conical dome on its side, it was larger than she thought it should be.

At her feet were multiple holes of various sizes that dotted the ground. Strangely, they appeared to be perfectly round, with one big enough for them to fall through.

Peggy scowled when she noticed the edges of these pitted openings. Unlike the natural crevice in the beacon room, these were very smooth, almost as if they had been worn away by something.

She crouched by the largest one and carefully ran her fingers around the edge. Next to it was a spattering of smaller holes, a few barely the size of a pencil's eraser. Frowning, she aimed the scanner at what she saw. "This looks to have been eroded, but I have never seen anything like this before. What do you think caused it?"

Howard answered, "By the spatter pattern and how the holes were melted, perhaps some harsh chemicals were splashed onto it."

Peggy shined her light into the largest hole, and it appeared to go down far enough that her beam of light was lost in its depths. She wondered how deep it truly went.

"Miss Carter, over here," Jarvis' eager voice dragged her attention away from the oddness of the floor. Then, mindful of the dangerous pits, she gingerly made her way over to him.

Jarvis was staring at a multitude of small glass tubes, their flat ends facing outwards. Since the Lighthouse was toppled over, the puzzle was at their eye level. A few vials were broken or possibly smashed, and the glass pieces glittered when Jarvis aimed his wrist unit at the floor.

Peggy quickly counted the rows of tubes and found that it was composed of seven across with the same amount downwards. If all had been intact, that would have made a total of 49 glass cylinders present.

Howard could barely contain his glee when he ordered, "Wave the scanner over it, Peg."

While she did so, Jarvis stared at it. He mumbled absently, "If I did not know any better, I would say that there was some sort of engraving on the surface of these tubes." But either intentionally or due to being centuries old, whatever image was etched inside the glass was too faded for the naked eye to see.

After some thought, Howard answered, "You're right, Jarvis. There seems to be an image, but the scanner can't pick up what it is. I can't even tell if it is made up of individual pictures or if it makes a larger one as a whole. Professor, any ideas?"

They heard the Professor tsk, "No, I am afraid not."

Wondering if a tactile approach would work, Peggy gently rubbed her hand across the surface, but she could not feel any indentations. She smirked, "So, I guess we just hit them randomly and see what happens?"

Sighing, Howard admitted, "I am afraid so, Peg. But use your best judgment. Knowing how these tests work, it could spring a trap. Based on the holes in the floor, one wrong move could get you melted."

"Right, let's try this one." Exhaling, Peggy placed her hand on the glass tube in the top corner.

Just before she attempted to move it, Jarvis suggested, "Perhaps try the one in the middle instead."

Nodding, Peggy cautiously attempted to twist the center glass tube. It wouldn't turn in either direction, so she tried pressing it down. It took a bit of push, but she could lower the tube until the back part was flush with the wall. After that, the cylinder stayed in place, and nothing happened. All exhaled, relieved.

Though victorious, the image was only slightly more visible since it was now against a dark background. In studying the tiny picture, all Peggy could discern was that it looked like some wavy lines. To her, it was either part of some puffy clouds or rolling hills.

Nodding at Jarvis to be ready, she pressed the tube next to it, and it stayed down. It appeared that the images were linked to the other one, which meant that they were most likely looking at one big picture, not individual ones.

Jarvis inquired, "Anything yet, sir?"

Howard cursed, "Sorry, nothing distinguishing yet."

Assuming the image was of rolling hills, Peggy pushed the next one, but their luck ran out this time.

There was a rumble as the previously compressed cylinders slid back into their original position. Then, Peggy heard an alarming hiss.

Quickly grabbing Jarvis, she then threw them both down to the ground. Caustic chemicals suddenly shot out between the tubes, just barely missing them.

They watched, horrified, as the acids spray eroded more pits on the floor. Relieved to be safe, they exhaled, but their reprieve was only momentary.

The ground next to them crumpled away, and the large hole widened. Instantly, both had to roll away, or they would have fallen into the expanding gap.

Due to so much of the ground being eaten away, it affected the nearby walls. The room began to shake violently. Fine dust sprinkled down on them from above, and they heard a sharp crack behind them. There was a terrible grating noise as the small entranceway compressed in, making their escape route even smaller.

Fearing the worst, Howard yelled frantically, "Peggy, Jarvis, what is going on?"

The quaking motion roused something inhumanely large below in the subterranean cave. Bits of debris fell on it, but the creature returned to its slumber after the shaking stopped. Over the centuries, it had learned to be patient for its next meal.

Now that the room had finally settled, Peggy and Jarvis saw how they had entered had shrunk. They shared a worried glance at one another. At least the acid had stopped eating away more of the flooring, Peggy thought drily as she tried to think of the positive.

Hearing Howard's desperate pleas for an answer, Peggy reassured him, "We are alright, Howard."

He breathed out a sigh of relief, "Oh, thank God. What happened?"

Jarvis aimed the scanner at the damage, and Howard replied pragmatically, "They must be using acid derived from seawater." He added, "By the state the floor is in, I bet others have tried solving this puzzle before."

"Where are their remains?" Jarvis audibly gulped as his gaze quickly darted about the room. But he found no melted evidence of any intruders.

"They probably fell through to whatever underground chamber is below you," Howard supplied.

Exhaling loudly, Peggy said, "Right, well, we best finish this up before we run out of room and air." Once more surveying the glass tubes, Peggy made a mental note not to press that third one again.

Cautiously they got to their feet. Alas, to reach the puzzle now, Jarvis would have to hang onto Peggy to keep her from falling in. Making sure he had a good grip on her left arm, Peggy leaned over and pressed in those first two cylinders again. Her hand wavered, unsure of which one to try next.

Howard's voice cut through her thoughts, "Hold on, Peg, I was wondering about this. Obviously, there isn't any randomness in figuring this puzzle out, right? As you deduced earlier, if these were made as a test, then there must be a way to solve them where one doesn't end up in melty death."

"I am open to any suggestions," Peggy said. A mental clock was going on in her head, and she figured they had less than ten minutes of air left.

"Just don't do anything recklessly foolish, my dear," the Professor stated condescendingly.

Shaking her head in irritation, Peggy wished she could reach through the coms and throttle him.

They heard Howard tinkering, "I'm going to attempt something on my side. Maybe there is a better spectrum we could try. Just give me a moment to modify this."

Peggy did not need to remind him to hurry along. She swore Howard used up a costly couple minutes of air, but his eager voice finally informed them, "I adjusted the spectrum to its highest possible calibration and then some. Peg, I need you to move it across all the cylinders as close as you can. Hopefully, then I should be able to see something."

Peggy took the scanner from Jarvis' free hand and did as the brilliant inventor requested.

Howard sounded relieved, "Yes, I can see something now. Unfortunately, it's still too faint to get a complete image on our end, so you will still have to press them in. Alright, try the third tube."

She glanced at Jarvis, who shrugged and asked, "In which direction, Howard?"

"Have her use the grid method," they heard Spencer suggest.

"Yes, starting on your left, go down two squares and then go across three and press it in."

After following his instructions, Peggy did what he indicated. Thankfully nothing happened. Relieved, Howard then quickly fed her more directions. It did not take her long until she had finished most of the puzzle.

In that time, a portrait was soon revealed. An older bearded man wore a laurel leaf crown on top of his curly hair. A lightning bolt was on either side of him. Also, some archaic Greek words were cresting around his head,
almost like a halo.

Professor Spencer stated excitedly, "It's Zeus."

"So, our next stopover will be the Statue of Zeus in Olympia," Jarvis sounded rather proud of himself as he pulled Peggy back to him.

Peggy asked, "And what about those ancient Greek words, Professor?"

Spencer mumbled the translations to himself and then said, "It just reiterates that we should be looking for Zeus."

Peggy was about to leave when she noticed that the same peculiar hatch marks were now highlighted around the frame of the image. She inquired, "Professor, there are more of those odd symbols. These must be part of the treasure hunt."

Spencer stated, "Yes, you best get a picture of them just in case."

As she leaned over to get a better scan of them, Jarvis stated, "Miss Carter, I do not think we have time to catalog all of them."

Too intent on recording them, she muttered, "Sorry, Jarvis, but I think this is important, too." She would have sent him on his way, but she needed him as an anchor. Thankfully it did not take long to scan them all.

Stating her reasoning out loud, she insisted, "Since the clues have us visiting the Wonders in a certain order, there has to be a reason why. And with these symbols being one of the few constants, I am sure they are part of that answer."

Jarvis warily nodded, and his movements made her aim a tad off. She was about to give it another pass when Howard stated, pleased, "You got everything, pal. Best come back now."

As they both hurried towards the exit, Peggy wished that Howard had packed more than just those two mini-tanks. According to the tiny air gauge, they could use one now. She eyed the shrunken opening and nodded for Jarvis to go first. He was thinner, so if anyone were to get stuck, it would be her.

He began to protest, so Peggy reminded him, "Manners aside, Mr. Jarvis. But if I can't get through, you can always hand me a regulator from the bigger tank and then go for help."

Eyeing the smaller hole, the SSR Agent vowed that she would bring a crowbar with her next time.

Reluctantly Jarvis nodded and handed her the small pack.

As Peggy shoved the scanner back into the bag, she watched Jarvis squeeze his way out. Suddenly he stopped. She realized that he had gotten jammed in the opening.

Unfortunately, the earlier shaking had made the hole tighter than they had first suspected. So now Jarvis had a dickens of a time trying to pull through to the other side.

To free up her hands, Peggy shrugged the backpack on and then attempted to help her friend. At first, she tried to push him out, but he was too soundly wedged in.

Jarvis moaned at her, "Oh, I will never hear the end of this."

To take his mind off their dire situation, she quipped, "That'll teach you to have that extra helping of Crème Brulee last night."

Unamused, he replied, "Ha, ha. This is most embarrassing."

Glancing at her gauge, Peggy noticed that they had less than a minute of air. Knowing that panicking would not help, she said offhandedly, "Well, obviously, we can't stay here." So she began to shove against him harder, more determined than ever to get him through.

Alas, in their haste, some part of his wetsuit must have snagged on a rough patch, for Peggy heard a loud rip.

Frantic, Howard yelled over the comms, "Careful! Remember, those suits can be very sensitive—"

Too late, Jarvis' rubber suit tore. Instantly, the safety protocols reacted, and it started to inflate.

The swelling wetsuit nudged against the small exit hole as it quickly expanded. This extreme pressure began to crack the already weakened surface further.

Peggy watched in horrified fascination as spider-like fractures shattered up toward the wall overhead. Continuing its destructive path, bits of mortar dropped onto them from above.

Frantically she now threw herself against the bloated suit. Still, she could not budge her friend free.

Since she could not push him out, Peggy had no choice but to try to yank him back in. But by then, the suit was too well lodged. And still, it would not stop expanding.

Hearing Jarvis' terrified yelps, she pulled harder.

Suddenly, his engorged suit hit a sharp edge.

Boom, it exploded!

The resounding blast had both their ears ringing. It also caused more of the wall above to fall on them, only this time it was larger chunks of debris. With Jarvis no longer encumbered in the suit, Peggy jerked him back to safety just as a giant piece fell from overhead.

Stumbling backward off balance, the duo landed next to the deepest eroded pit. They both watched, dismayed as the hole beside them began to widen further, forming an enormous fissure.

Finally, the destruction around them ceased.

Peggy exhaled, relieved. Looking over her shoulder, she was shocked at the massive pile of rubble that now covered their only way out.

Suddenly, the mini air tanks beeped a warning that their oxygen was almost out.

With his tattered rubber suit hanging from his tall frame, a stunned Jarvis groaned beside her. Thankfully his swimming attire underneath had not been damaged during all this.

Sitting upright, Peggy tugged his bare arm worriedly and yelled, "Mr. Jarvis, are you alright?"

He wrung a pinky repeatedly in his ear and hollered back, "What, I can't hear a thing."

But Peggy could. She glanced up worriedly when she heard the sound of the wall overhead starting to buckle. Horrified, she watched as a huge section began to snap its way free and drop lower. Any moment, they were going to be crushed under it.

Just as the huge chunk cracked away and fell towards them, a desperate Peggy grabbed Jarvis. With seconds to spare, she rolled them both over and into the widened hole beside them.

Not being a shallow pit, they fell downwards into the darkened unknown.

As they tumbled in free fall, Peggy heard Howard's plaintive voice frantically yelling in her ear, "Peggy! Jarvis!"

Then the massive slab of rock crashed down over the fissure.

The signal was lost.
