The city of Atlantis was under siege.

It began with the inky black cloud of darkness that formed outside the city walls. And then, all manner of abominations sprang forth. Fish-like humanoids similar to the Gill-Man, but were too mad or insane to obey the queen's call. Instead, they obeyed only two gargantuan beings. The so-called Deep Ones called them Father Dagon and Mother Hydra.

With them was a colossal shark-like / serpentine creature that the Kraken battled. Leading the invading army was a figure with a mighty ax. He called the giant Leviathan, and himself The Executioner.

The battle was by bloodshed, until the gods made known their will. Kruu's people, the Atlanteans, fought hard and bravely. The Kraken roared and caused tentacles to bleed. The Gill-Man defended his queen, and in turn, she defended him. Yet the Deep Ones were unlike any threat ever previously faced before.

The twin titans Dagon and Hydra continued to ravage the city, the advanced technology doing so little to hold them back. The Kraken was forced to face three adversaries because of this. Meanwhile, Kruu and Psari found themselves facing off against the commander himself.

"There is no hope!" He cried. "Surrender the city!"

Never! The Queen cried. You have no right to invade my home AND my people!

She fought with all of her Syren Magic. She was able to match the Executioner, and even surpass him, but it was his unexpected giant form that caught her off-guard. Kruu had never fought anything this big since the mantis, let alone the Kraken itself!

The Gill-Man fared no better, as the Executioner managed to slam the Creature into the ground under a giant fist. All seemed nearly lost.

Recovering, Kruu noticed a Deep One, having snuck into the city undetected, springing back out! The Executioner turned its attention to it, and as he shrank back down to normal size, the fishman began speaking in an unknown language.

"It's not there? What do you mean?"

More strange words, ones that not even the Gill-Man knew of. The Executioner spoke no words. With a single slam of his ax to the ground like a staff, he ceased the onslaught.

"Gn'thornythh of Y'ha-nthlei!" He called. "We have the wrong city. Enough time has been wasted here. Now, find the REAL city! The masters demand it!"

Almost instantly, the army stopped what they were doing and swam off, the Executioner following and leading them. In mere seconds, they were gone, leaving the Atlanteans to repair the damage dealt. Yet the queen was puzzled.

Wrong city? Kruu asked. What did that thing mean by 'the wrong city'? Atlantis is the only sunken city we know of!

The Gill-Man was silent. And then, its eyes widened. What it said to Kruu shocked her.

Back in the Amazon…yeah, you said you came across some kind of ancient city long before Atlantis was built! Way back in the Denonian age! Do you…really think they could be referring to such a place?

The Gill-Man shrugged.

This is bigger than I expected. Bigger than all of us. Kruu noted. I have to inform the surface warriors. Perhaps THEY may know something about all of this…

Looking back, Kruu realized that they MUST have been talking about R'lyeh. Home to the Great Old Ones. And graves to many more. She recalled one of Lovecraft's tales about how, in his universe, Cthulhu was freed by unlucky sailors. One man, Gustaf Johansen, managed to stun Cthulhu by ramming his boat into him, long enough to escape before the Great Dreamer could reform. The city sank with the being, but there was a warning that it would rise again.

"Howard," R.L. Stine was questioning the visitor. "How much do you know about this universe? And…what was yours like?"

"Your Lovecraft was but a harmless fiction writer, with one of his only friends being Robert E. Howard, publisher of Weird Tales. I suppose he inspired you to become a horror author himself, much like Edgar Allen Poe did him. If I had to say one word about this reality, it would have to be…merciful."

"And just what do you mean by merciful? We certainly don't have any beings of cosmic madness here. Just various monsters of all manners and origins."

"It's not the monsters I mean when I speak of this. The most merciful thing in the world, I think, is the inability of the human mind to correlate all its contents. We all live on a placid island of ignorance in the midst of black seas of infinity, and it was not meant that we should voyage far."

"So basically, compared to these great beings, our lives are just blinks of an eye."

"They are more than that, Robert. Compared to them, we are…insignificant. To them, we mean nothing. We are inconsequential. Nothing but dust and ash filling the horizon. You should be lucky to have such harmless monsters. Mine show no such mercy."

"Oh, we've dealt with merciless monsters before." Van Helsing stated. "Like Dracula. I bet HE was fiction in YOUR universe."

"He was. We were all fiction, as my universe was but Azathoth's imagination. It ended when he awoke, when the last star burned out from the heat-death of the universe. Now, should we fail, all will become and remain fiction. Through madness, reality becomes illusion. I will admit that not even I know how to stop and destroy such a great and powerful being. But we have to try. Before his corruption and chaos spreads. And ensure that it meets no other eye."

"Okay, we're finally here." Dr. D stated. "47 degrees and 9 minutes south, and 126 degrees and 43 minutes west. But I'm not seeing anything in the distance. There's no charted islands on this area of the map. Like it shouldn't exist."

"It's a sunken city, doctor, not a wild goose chase." Lovecraft stated. "We will handle diving under. It's key that we never allow that city to surface."

"My Air Bubble spell should work." Kruu added. "Amplified with other magic, this will both act as a shield AND allow us to keep breathing air, separating all water around us."

The team only prepared their armor and monster forms, readying themselves to dive in. But another headache from Lovecraft began to signal something. And something like an odd inhuman sound came from the waters.

The echo. The deafening bellowing echo. All went still.

"Something's wrong." Lovecraft said in alarm. "We're not alone. Something's in these waters!"

By the time Cory saw what it was, it was far too late.

Massive tentacles rise from the sea, with mouths with razor-sharp teeth and many eyes! There was a low bellow as Conrad quickly cast a defensive barrier around the ship so that the tentacles couldn't grab it and sink it to the ground!

"AH!" Mirpo yelled. "Kraken! It's the Kraken!"

"Wait, no, this CAN'T be the Kraken!" Kruu realized. "We've already got one!"

"So what IS that thing?!" Arach-Kid called out.

"Cthylla." Lovecraft stated. "The Secret Daughter. And known by the Greeks as Scylla."

The Midnight Society sprung into action, beginning to attack and slice the tentacles apart. Lisa only felt that if they grabbed you, what happened next would be FAR worse than a hentai.

"So, you said this is a secret daughter?" Agent Z asked. "Of who?"

"Of Great Cthulhu himself!" Lovecraft said. "Should the Great Old One ever perish, she will give birth to him so he will be reborn anew!"

"Wait, she's gonna give birth to her own DAD?!" Eddie yelled. "EW! There goes the space-time continuum! Wait, does this mean she's gonna be both his daughter AND his mom?!"

"Well, just be glad she was the offspring of Idh-yaa and not of Cthulhu's sister Kassogtha, like Nctosa and Nctolhu!"

"AGH! Double gross!" Hannah yelled. "These old gods do incest too?! I KNEW tentacles were part of the forbidden Rule 34 for a reason!"

"Hey, you said that Cthylla is also Scylla?!" Grady asked. "Then…who's Charybdis?!"

"A hard place is the LAST thing we need!" Erin Wright yelled. "Or a rock! Because I can NEVER get those two right!"

"The cult hides all information about the Secret One! Originating from the star Yoth, she is heavily guarded by her father's minions on Yhe!"

"I bet you're talking about your own universe right now!" Super Duper stated. "Here, she must be another one of Fear's minions!"

The tentacles were zapped with bullets, magic, and energy, the eyes squinting shut once they were hit. Demonic hellfire burned them, forcing the tentacles to retreat into the water! Yet more surfaced, slamming against the barrier with such force that it was getting on the brink of shattering completely! At this rate, the boat would sink within minutes!

"Agh! This thing's tough!" Cory yelled. "I think I'm getting a splitting headache!"

"Argh! Dammit, my head!" Lucy Dark yelled. "Why won't these stupid voices stop?!"

"Such a terrifying monstrosity!" Arragotus yelled. "Just what exactly IS this beast?!"

"Of COURSE it's terrifying!" Lovecraft yelled. "Cthylla is one of the Great Old Ones themselves!"

He froze, realizing what he said. Great Old Ones? OH NO!

Those who even looked at a Great Old One, and any greater, would go mad! Yet Cthylla didn't reveal herself fully, and they had only HEARD her. Yet the damage was beginning to be done. Wargon seemed to be laughing from the carnage he was causing. But that WASN'T because of the carnage…

"NO!" Lovecraft cried. "EVADE YOUR EYES! YOU ARE SEEING THINGS! NONE OF THIS IS REAL!"

He began channeling one of his most powerful spells yet. With a yell of desperation, he slammed the dark green orb onto the boat, sending out a pulse of magical energy! Instantly, the hallucination and illusion faded, the imaginary tentacles becoming non-existent as the chanting in the distance stopped.

The barrier faded, and everyone dropped to the ground in desperate exhaustion. They had been forced to spend all their magic on what they thought was an imminent threat. But nothing had been there the whole time.

"That…was too close." Frankenstein gasped. "But…where did she go?"

"She was never here." Lovecraft said. "With her call alone, she put us into a trap to stall for time. As well as force us to expel most of our magic. That star charm must be waning in power if such hallucinations are happening to us while we are in the waking world."

"If the Great Old Ones are making such an influence here," Sasquatch said. "Then that means that the Mystic Realm and Dream World may have both fallen. We must hurry! They could be in the city at this very second!"

"No time to waste then." Van Helsing stated. "We're going diving!"

And with that, he was the first to leap into the black waters. They would be going a hundred fathoms under. And there would be no telling if they'd ever come back…
