If you see a corpse on a hill you should avoid it. Why you ask? It could be a Coth. Coth is short for Corpse on the hill.
A Coth is a big Trap plant. The corpse is not a real one, but a part of the plant used as Bait. If an animal tries to eat the corpse the middle part of the plant will redact. This area differs, but is usually around 2.5 times as big as the 'corpse’.
The animal will then Fall into the coth’s stomach area and gets digested alive. The hill you see on the outside is actually earth that was pushed up during the coth's growth.
Some Varints are considered Mael kin due to the form of their bait.
