The Orca Revolution!

Somewhere hidden inside one of the 7 Great Seas, the Dungeon of Souls.

Like every other one of the 7 Great Seas in Oceania, the Dungeon of Souls was unique in a way that separated it from its 6 other siblings. The origin glow of this Great Sea was a spooky dark green mixed with black.

But unlike its 6 other siblings, the uniqueness of the Dungeon of Souls reached such an extreme degree that it was uninhabitable to a lot of beast species.

Only a select number of mutated beast species could survive and thrive in this extreme water body. Extreme predator species like Death Dragons, underwater Wraiths, and zombie sharks were the ones that could thrive here.

The Dungeon of Souls was made specially to favor these types of predators. Though in contradiction to rumors, it was not filled with undead energy all year round, it was a fact that this great sea was modeled for mostly undead beasts.
