Tieflings

Tieflings are a playable race in the Woorfel campaign setting. They result of either the child a fiend slayer or the union of one race and another tiefling. Slaying fiends in Woorfel magically enhances one's ability to do so. It's not uncommon for a fiend slayer to eventually develop fire resistance or the ability to see in the dark, after some time a person will begin to resemble the fiends they slay, one's future children will often gain these adaptations in a greater abundance than the original slayer.

In many places across Woofel, tieflings are associated with nobility. As knights would return to their kingdoms after long adventure they would find their children bear the signature horns. Some kingdoms are lead by tieflings. Peasants and other commoners would view these children as protectors of the land adapted to fend off creatures as their noble lineage had done before. A mixture of pride and healthy fear is the common reaction to a tiefling. These attitudes leave tieflings to enjoy comfortable early lives, but are pressured to venture out and prove their worth upon reaching maturity. Tieflings live with an expectation to be bold, strong, and unconquerable. Most often Tieflings revere Vonkeros, the source of the magic that allows mortals to adapt to those they defeat.

The adaptations of a tiefling largely depend on the type of devil/demon their line has a legacy of slaying. An archer could very well find their child has wings after slaying many flying demons etc. Consult relevant source books and use this to help inform any sort of tiefling variant chosen.
