Distribution: Rare and widely scattered
Game Rules: Use standard Tiefling ancestry rules
Tieflings are mortal people whose lineages carry a persistent infernal influence associated with Vharath. Known lineages have arisen from ancient contracts, prolonged exposure to infernal power, deliberate transformations, and other enduring relationships between mortals and devils. The event that altered an ancestor does not by itself give Vharath a claim over later descendants.
Tiefling traits can persist for generations and may reappear after long periods in which a family shows few obvious signs of its infernal inheritance. Their appearance often reflects the character of the original influence, producing considerable variation between bloodlines.
Tieflings have no single homeland on Kor Sirok. Most are born into the societies of other mortal peoples and share the language, customs, and loyalties of those communities. In regions with strong memories of infernal bargains, visible Tiefling traits can carry social or religious significance that may be absent elsewhere.
