Variphor

Variphor is an entity that existed somehow between the worlds; between "existance" and "non-existance". It was discovered by the Yalahari in their quest for knowledge. It had vicious nature, however, and soon the Yalahari's discovery turned against them; manipulating them into killing each other one night, when most of the Yalahari were killed. The rest then fled their island, which was left to their former minions.
