In Atlantis, the other three ponies had sent the message to Leon. They then headed outside the Great Hall, where Empedocles was waiting for them. "Spirit, we require your help in dealing with the Big Stallions near the tomb. We can't do it without getting shot down by their rivet guns. With that amulet, you can help us stop them. Please, we beg you."

It's the least we can do for them. They hadn't arrested us, even after learning we weren't mermares. And they gave us the diagrams on the Big Stallion. "Of course! How many are in the area?" Doc asked.

"Three. One of them is fairly weakened, but the other two have no damage whatsoever. We need to capture or eliminate all of them so that they can stop attacking the tombs. I'll guide you to them, but be warned; the only effective weapon you have is your magic." He then guided them to a chariot, and they all left the city towards the caves.

…

After ten minutes, they stopped at a cave position where many guards were posted. As they made their way inside, they were shown the horrors of war. Many of the guards were wounded, and those that weren't were treating the wounds and removing rivets from many of the mermares. The group also saw many body bags deeper inside the cave topped with clamshells which carried their identity. They could not believe their eyes; ponies killing each other in combat. These Big Stallions must be destroyed, along with the ponies inside them. Who could do such a thing? Doc asked himself.

"Who's in charge here?" Doc asked. The guards looked towards him, and pointed towards the pony in the back of the cave. He looked up, and approached Doc. He was a pale yellow mermare, with a short, white mane. His eyes were a dark purple, and they were weary.

"I am. I'm Admiral Selachii. We need your magic to stop the Big Stallions at the tombs," Selachii explained.

"We'll do it, but we'll need your help as well. Here's what I think we should do; I'll use my magic to slow or disable the Big Stallions, and that's when you'll come in and damage its weak points. Cloud Runner, you'll be the distraction. Annabelle, you'll be part of the hit-and-run squad. Sound good?" Doc asked.

"It seems simple enough to do. What magic will you use to slow them down?" Selachii asked.

"I can't use electricity down here, so I'll slow them down with some ice. That's when you guys charge their ankle joints and destroy the armor."

"Good. If it all goes well, we'll have the tombs back by the morrow," Selachii commented.

"Let's go," Cloud Runner stated.

…

A convoy of about seven guards and the Spiritual Searchers travelled south for a good ten minutes, before Selachii stopped all of them behind a rock. "They are up ahead. Doc, will you initiate phase one of your plan?" he asked.

Doc looked past the rock and quickly hid again. "There's one right there. He's huge!" Doc whispered. He took out his amulet, and powered up. "I'll start using my magic." Doc slowly crept towards the end of the rock. He slowly peered out from the edge, but found that the Big Stallion was gone. Where did he go?

CRASH!

Out of nowhere, a drill struck next to Doc, almost killing him. He looked up in shock and saw that the Big Stallion was right behind him, viewports glowing bright red. It had stuck its drill into the rock, and could not move. He quickly acted by using his magic. His amulet shone a bright green, and his horn glittered brightly. He then took aim at the Big Stallion, and fired an incredible beam of light at it. The light came into contact with the Big Stallion, and it froze over completely. The guards now took advantage of the situation and charged towards the weak points of the Big Stallion. One by one, the joints of the armor fell apart until all that remained of the Big Stallion was an earth pony. The guards had seized the pony, and continued their trek through the tombs.

OK, that's one down. We need to find two more. They're most likely within the tomb, mining for BETA. "Stay alert. They will be deeper within the cave," Doc advised. The guards seemed preoccupied with picking up the drill from the Big Stallion, which included a flashlight. They easily brought it to the front of the convoy, and travelled slowly deeper into the cave. All of them were terrified, as the next Big Stallion could sneak up on them at any moment. This reminds me of some horror title that I've seen before. Doc thought.

They then saw it; the next Big Stallion, lumbering casually and drilling the cave wall. It then stopped, reached inside, and pulled out a white, glowing substance. Doc motioned to the guards to get ready. He took aim at the Big Stallion, and readied the next charge of ice. He blasted the Big Stallion, and it froze over. The guards then attacked the weak points of the armor yet again. It completely fell apart, and the pony inside floated to the roof of the cave. The guards then proceeded to go deeper into the cave, but not before being stopped by Doc.

"Hey! We can't just leave this pony like this," he said.

Selachii then intervened. "Of course we can. The pony is dead, anyway. We must find the last Big Stallion. Now, it's possible that it may be somewhere…" He did not finish his statement before he was pierced through his back and stood motionless. The object that was used to pierce him was not a drill, but looked more like a needle. It was removed, and Selachii was dead before he hit the ground. Every pony stood shocked and shrieked in horror.

"Holy shit! The admiral's dead!" yelled one of the guards.

"Every pony, stay close together and keep the light shining!" Doc ordered. They followed without hesitation. They didn't know what this last Big Stallion had that made it so stealthy, but they would dare not find out. Doc used his magic to illuminate the small circle of ponies. That thing used to kill Selachii wasn't a drill. That Big Stallion isn't damaged; it's a different model. They're possibly used to wipe out traces of the guards. Doc turned towards Cloud Runner. "Cloud, this one's not like the other two. This one's designed to sneak up and kill unwary ponies. Whatever you do, don't leave the circle," he warned. Only he knew how one fatal mistake could end up killing them all, and he tried to devise a plan.
