Deviladon

Lore
There is a reason a light is required when entering a cave in the region of (blank). Deviladon often live in caves, swimming in the shadows scouting for its next victim. If someone is so unfortunate to be in a cave without a light, they better hurry on out of there, because if this creature who is strong enough to crack boulders and has a bite force strong enough to rip metal is there as well, he won't be far behind.
