Troll

True troll is a species of hominid part of the family, Archohominidae. They fill a similar niche to false trolls, but are much friendlier and are not willing to harm any sapient species nor beings, except vampires. They have the ability to roll into a ball and their skin looks like stone to give them a rock-like appearance to protect themselves against most predators. They are omnivores that feed on the same kind of food as common humans.
