The Tainted, otherwise known as tainted ones, are the bastard immortal children of the union of one of the Fallen and a human – most occurred during the War in Heaven, though others have been birthed in much more recent times..
While most were killed, they are still found from time to time in dark and secret places, and are cunning, manipulative and while they have a human aspect, are essentially creatures of pure evil and malevolence.
Their form varies, and is essentially a mix of human and fallen characteristics – some have huge bat like wings, the body of a snake, horns, barbed tails or any mishmash of human and fallen physical features.
All of the Tainted have psionic abilities, though how they express varies from individual to individual just as some of the Tainted are more human in appearance than others. Some are able to directly read the minds of their opponents, others are able to subjugate another to their will just from the merest gaze, and others still use their power to generate psionic energy that crashes on to their foe in crippling waves of nausea and pain to anyone who dares meet their inhuman eyes.
The most famous of all the Tainted is the son of the first DeathKnight, who went on to become the second DeathKnight in his own right, Nachrael, the Desecrator. This led scholars to conclude that the first DeathKnight, by virtue of the powers of the Brand of the Fallen, had effectively become a new type of the Fallen himself.
