The Demon-King Yangtzu

Mastigos, Tremere Lich, Former Guardian

When the Mortivora Cult was discovered, the corruption within Chicago's Guardians of the Veil was brought to the stark light of justice. As the Consilium hunted down the Guardians that were involved in the eugenics experiments, the Abyssal cults and the other dark, left-handed practices, many of the worst Guardians slipped into their Labyrinths and vanished. Among these was Yangtzu, the so-called "Demon-King". A master of goetia, he sought out the power and immortality of the Tremere Liches, and when the time came for him to stand trial for his heinous acts, he all but vanished.

It would be several years before he would re-appear in Chicago's Chinatown, possessed of wealth and power so great that he's turned Chinatown's Occult Underground into his own personal fiefdom - a clearing house to feed his hunger for wealth, power and souls. He rules his empire - both the dark, occult side and the ruthless criminal enterprises - with ruthless efficiency, hounding his foes with demons drawn from their worst fears, undead assassins and the destruction of their very souls. Still, he is not all powerful, and the groups that once lived in harmony in Chinatown now work as secret societies, each working to check his power and keep him from complete dominance.

Appearance

Yangtzu appears as a wiry, dusky-skinned little man with very narrow, squinty eyes. He has long, thick glossy black hair that he usually wears tied back and his explorations of the depths of the Astral Realms have tainted his body somewhat, leaving two small horns on his head - just above his hairline and barely noticable.
