Simultaneously more and less than mortal, tieflings are the offspring of humans and fiends. With otherworldly blood and traits to match, tieflings are often shunned and despised out of reactionary fear. Most tieflings never know their fiendish sire, as the coupling that produced their curse occurred generations earlier.
The taint is long-lasting and persistent, often manifesting at birth or sometimes later in life, as a powerful, though often unwanted, boon. Despite their fiendish appearance and netherworld origins, tieflings have a human’s capacity of choosing their fate, and while many embrace their dark heritage and side with fiendish powers, others reject their darker predilections.
Though the power of their blood calls nearly every tiefling to fury, destruction, and wrath, even the spawn of a succubus can become a saint and the grandchild of a pit fiend an unsuspecting hero.
No two tieflings look alike; the fiendish blood running through their veins manifests inconsistently, granting them an array of fiendish traits. One tiefling might appear as a human with small horns, a barbed tail, and oddly colored eyes, while another might manifest a mouth of fangs, tiny wings, and claws, and yet another might possess the perpetual smell of blood, foul incenses, and brimstone.
Typically, these qualities hearken back in some way to the manner of fiend that spawned the tiefling’s bloodline, but even then the admixture of human and fiendish blood is rarely ruled by sane, mortal laws, and the vast flexibility it produces in tieflings is a thing of wonder, running the gamut from oddly beautiful to utterly terrible.
