Ohmu, also known as Gorgons, are enormous crustaceans native to the Toxic Jungle, a near global forest of fungi and giant insects.


Ohmu are amphibious and highly protective of their young. Their blood is blue. Their hides are extremely tough and can be used to make swords, as their exoskeleton is very durable, stronger than the toughest of ceramics and their eye casings are sometimes collected.

An enraged ohmu.

Ohmu protect the Toxic Jungle, violently pursuing anyone that harms it or the creatures that live there. They can become so enraged that they can destroy entire cities when travelling in groups. They also spread the spores of the fungal plants, allowing the Jungle to grow further.

Ohmu operate in a hive mind, and can even communicate with some individuals. They are also capable of healing others by utilizing a mass of tendrils located at the front of their heads.
