It's dark and musky, there isn't light save for the bioluminescent sea flowers dangling from the ceiling and the eerie ambient light cascading from the huge aquarium tank in the back of the auditorium. It's filled with stagnant, stale water. The glass is broken and spider cracks run down the front of it from top to bottom. One protests they go back, the other claims it's been like this for awhile so it should be safe. Once they find the flare they were so desperately searching for, they meet near the front of the run down exhibit. They light the flare, ecstatic to finally have a source of sustainable light even if it be for only 15 minutes. The red smoke billowing up and illuminating the grimy and moldy state of the tank. Then they see it. A silhouette growing and growing in the back of the tank, a silhouette of something that doesn't seem anatomically possible. The spider cracks get bigger as spurts of water start exploding from them, they take a step back but they know they messed up. There was something in there and it was bigger than 60 feet tall.
Tying in with the Cyber Gamer Illustration, this was a scene I had imagined for when Wiley is trapped in the video game with the main protagonist; trapped in an abandoned aquarium named Mariana's Grotto that houses creatures found in the deepest depths of Mariana's trench. Ever since being abandoned however, the creatures adapted on their own to their environment, creating dangerous combinations such as jellyfish thriving to hi-jack nervous systems using neurotoxins and chimeric Megalodon who can't see it's prey but can smell it from miles away. All while Wiley is trying to figure out how virtual reality can feel so frighteningly real, because this might actually kill him.
This megalodon, dubbed Felix by vandals, has adapted in the pits of Mariana's trench by growing limbs so when the pressure at the bottom of the ocean gets to much to swim, it can drag its self across the floor of the ocean. It can drag it's self just as fast as it can swim. It's skeleton and skin are rock hard.
