The Skilosh demons are humanoid in appearance; bald with chalk-white skin and sporting two red stripes which run down their foreheads to their eyes, then back behind their ears. Directly in the back of each Skilosh's head is a single third eye.
Skilosh inject their spawn into the back of a humans skull with a powerful long forked-tongue. Within only over an hour the spawn grows into a single eye (as seen on the full-grown Skilosh) which is connected to the human's vision via the gestation period, which lasts only days. Once the gestation period is complete, the Skilosh spawn hatch full-grown from the human's skull.
