The Black Triune are the rulers of the nation of Nidal and are based in its capital of Pangolais. No longer fully human and caught between mortal life and undeath, the membership of the council has remained unchanged since the beginning of the Age of Darkness in -5293 AR, and none has sought to challenge their authority in all those years. The will of the Triune is enforced by General Mykos Roarik and his Adamant Company, who carry out their wishes with brutal and unswerving loyalty. All three members of the Triune are also members of the Umbral Court, Nidal's ruling body.
Following the devastation of Earthfall in -5293 AR, the tribal leaders of what is now Nidal prayed to the gods to deliver their people from extinction. They were heard by the newly freed Zon-Kuthon, who had recently emerged from his exile to the Plane of Shadow somewhere near modern-day Ridwan. The Midnight Lord offered his protection in return for their eternal servitude and that of their descendants. The leaders agreed and were transformed into the Black Triune.
The Black Triune consists of a cavalier and sentinel of Zon-Kuthon, a ranger and exalted of Zon-Kuthon, and a witch and evangelist of Zon-Kuthon. Their true identities are virtually unknown; all three have carefully erased all records of their lives, no one knows their names, they rarely appear in public, and they usually obscure their identities with shadow magic in private audiences. Scholars who try to learn too much often meet grisly ends at the hands of the Black Triune's agents.
