Tiefling

Tieflings are much like Aasimar in the nature of their existence. They are humanoids with a clear streak of demonic blood, a counterpart to Aasimar. Tieflings are not born in the same way that Aasimar are, via demonic heritage. Demon blood is subversive. Therefore, it is nearly unheard of demon blood to last in the open for more than a generation. Instead it tends to function below the surface as a powersource for sorcerers. Tieflings do, however, have tiefling children. The Tiefling population of Choll is exclusively a result of an event during the Upheaval. A wizard attempted to bind the demons, devils and angels to the material plane in order to stop the war by removing the pawns. While the first attempts were successful, his first attempt to bind a demon lord backfired. The entire region exploded in a wave of raw demonic energy which slightly corrupted every human. Their minds however were unaffected. Beside the change to appearance, they were completely cut off from magic. While other magics can affect them with some effort, they are unable to cast spells, divine or arcane They also can't use magic items that require a spell completion or spell trigger devices. They can activate other magic items just fine.

This has caused a curious change in Caspa, homeland of the tieflings. Where other races turn to magic, tieflings turn to technology. The race sports some of the greatest gear heads, tinkerers, scientists and gunsmiths in the archipelago. The nation of caspa even holds colleges devoted to psionics. Tieflings and Aasimar tend to get along rather well curiously. Aasimar realize tieflings are not inately evil, just as they are not inately good, and the races find many points of common ground. Thankfully in the Archipelago, tieflings are widely known to not be evil or devil spawn per say, though beyond the islands who could say.

Racial Abilities

Tieflings function as per the standard pathfinder rules with two exceptions.
 * Tieflings can not play any spell caster class. They can not be Bards, Clerics, Druids, Sorcerers or Wizards. They can be Paladins or Rangers, but they must give up their spell casting ability (speak with your GM about getting something small in return, perhaps a bonus feat at each point you would gain access to a new spell level.)
 * Tieflings do not gain resistance 5 to cold, electricity and fire or the darkness spell like ability. Instead, they gain spell resistance 11+character level.
