actually, I decided to re think it over a little bit, so I changed the idea, so the leviathan thing has 8 jaws.the algea has little glowing blue bulbs which the peepers eat. Actualy, I changed the idea to fit in with the game's story. The biome was created by the precursors, as a test zone, using some liquid precursor crystal and inserting it into hundreds of different fauna. This made the ones surviving immune to the carrar, but the issue with this created immunity is that it not only kills the carrar, but the creature as well, out of 5,000 peepers injected, only 300 mutated and survived. I changed the idea of the sike trap, so that the pecursors injected spike trap seeds with this lquid crystal, changing it. The reaper leviathan proved to be able to survive it and mutate. this biome is kept in one of the precursor bases, with a secret entrance containing 4 doors, to contain the acid water of the biome.

The precursors realized that the liquid crystal wasnt a cure, but was a preservative, creating the biome in case nearly all life of the planet dies because of carrar and lack of enzigm 42. since extracting the liquid crystal out of the fauna's blood stream, would revert the mutation. So the biome was the precursor's plan B incase the containment of carrar failed.

SO the reaper appears in small groups, and makes nests.

So I decided to add a second portion to this biome, it is a nutrient rich area in the Material zone. A cave in the biome leads to this subsection, instead of having green acid flowing, glowing blue nutrient rich liquid flows. THis was created so that the precursors could put more mutated flora here, and they wouldnt die of lack of nutrition.
