Tiefling

In a broad sense, they appear humanoid, a bipedal tetrapod. Though, that is where the similarities usually end. Tieflings might also have long horns on their heads which can vary in appearance to that of a goat, to draconic. They usually have long non-prehensile tails which twitch and move in accordance with their emotional state. The lower body is also variable, ranging from completely humanoid, to digitigrade, to even hooved.

Strangely, this species does not have an easily traceable genetic map. Tieflings are often born to completely average sapients, and children sired from tieflings can be completely average representations of the tiefling's parents. Scholars and researchers have published theories, however, no consensus has yet been achieved.

Tiefling children grow at rates that are average to the parent species, though at a slightly accelerated rate, usually achieving sexual maturity and adulthood a couple of years earlier than the parent's species.

Superstitious country folk will sometimes use tiefling horn as a remedy to cure anything from indigestion, to impotency. Tieflings never have their horns cut willingly, as it is an extremely painful act.

Most commonly found in the Pax Nevarrum, but can appear in any settlement.

Often have a dash of wit and cleverness to them.

All tieflings have the darkvision trait and can see in the dark up to approximately 60 feet, in a monochromatic lens.

Tieflings speak the language of whatever land they come from. However, they also seem to have an "ancestral" language that is understood universally amongst themselves. This language is never formally learned and is known instinctually by tieflings. The language is difficult to replicate by non-tieflings and is commonly referred to as "infernal" due to parents incorrectly assuming the child is possessed by spirits.

Despite being viewed with fear and suspicion by most sapients at a large scale, tieflings are quite charming and are often able to ingratiate themselves into social circles of any class. There are two exceptions to this.  

The Radiant Empire

Tieflings are viewed with severe prejudice in the Radiant Empire—even more so than other minorities. Strangely, most Radians could not tell you why they are treated so poorly. They simply are.   Aasimar: There appears to be some form of an ancestral feud between the tieflings and the aasimar. Despite having shared experiences, they refuse to cooperate with each other. At best, they will exchange venomous words and at worst, they will attack each other on sight. Even those with pleasant and innocent personalities will feel this grudge.
