Tieflings

Tieflings have descended from demons, they have decided its time to change their ways and repent by dispelling the world from demons, devils, and other creatures from the beyond. Tieflings normally have horns and tails, and occasionally have wings. These warriors tend to have a bad aura, people severely dislike them, tieflings tend to take on classes of mystery, like thieves, or necromancers, common disliked classes. Rare tieflings have an elemental twist to them so they have the skill to cast fire or freeze raging orcs,

but I have never countered a tiefling with a light element in them. Some tieflings don't have human appearances but as a researcher I study magic and creatures. I couldn't limit the tieflings linage down to a certain demonic race, personally I think can be any demon with horns, wings, and a tail.
