Based in a high fantasy world called The Primeval Terrain. Hybrids are human/animal beings that have been feared, shunned, and worshipped since time immemorial. Hybrids combine the intelligence and perseverance of humanity with power and instincts granted by the animal kingdom. They take on the traits of an animal (mythical or mundane) such as wings, claws/talons, scales, tails, horns, enhanced senses, etc. Only powerful hybrids have Sigil Stones.
