The Conclave is a band of mystics that were tied to the disruption of the Ethian cycle and the destruction of the landmarks. Its known members include Hycanthus, Haag, O'ising, and their leader, the now Greater Red Dragon Yudhishthira. Former member include the ice wizard Maklak who is imprisoned in ice on the Elemental Plane of Water.
Originally appearing during the Reflection Incident, the group also played an important role in the Birth of Destruction, resulting in the creation of the Goddess Makali, and were obviously at the centre of what came to be known as the Conclave Reckoning.
