The Tiefling Clans
Tieflings are the twisted descendants of mages that dabbled in the infernal magics. In the aftermath of The Great Marring, many Tieflings were hunted down and killed by groups who blamed the cataclysm on the Tieflings in a movement known as The Night Purges. As a result, most Tieflings fled underground, into the treacherous Undercaverns, where most do not tread. In the tunnels, they formed a clan based society rather than any unified government due to the scarcity of resources. A basic unwritten code of conduct is held between the clans to prevent extinction of their race. Most clans are small, roughly 20 people in size, although in some of the larger, safer areas clans as large as 50 can be occasionally found.
Tieflings tend to be clever, cunning and quick creatures by necessity of living in The Undercaverns. They have deep bonds with clan members, but are often distrustful of outsiders. The vast majority do not practice the infernal arts of their ancestors, despite the prejudicial claims of many topsiders.
