Tiefling
Tieflings are Humans who have some sort of blood originating from the Nine Hells, this might be old blood from many generations ago, or even as recent as a Devil being a parent of the Tiefling.
The way a Tieflings looks varies vastly, from very reminiscent to their non-Hellish racial heritage, or more like their Devil progenitor.
Tieflings exist across all walks of life, from lower to higher classes, and can be found anywhere in the world. There’s never been a proper society of only Tieflings, as the individuals usually reside in existing ones.
Tieflings might try to reconnect with their Hellish heritage, offering the service or searching for answers, while possibly even returning to the Nine Hells. Most tend to reside in regular society however, trying to live their lives despite the discrimination they might face due to their heritage.
