The Triad consists of the good-aligned deities Bastion, Tyko, and Rem.
They are a particularly powerful alliance that was one of the major forces behind the founding of the Triadic church, and their splinter group, the Triadic Knights. Several crusades were launched over the course of history in their name.
They reside in the 2nd layer of the 7 Heavens known as the Hall of Heroes.
