Bandur Etrevion
Bandur Etrevion was a dark mage who founded the theocracy called The Dark Path, and was widely regarded as one of the most profound scholars of his time. Though a human born of lowly origins in the mid-6400s Second Era, he was able to learn the black arts by swearing fealty to the Empress Kadaena. The Empress was killed thousands of years earlier, so it would have been through an intermediary, most likely her daughter who was his contemporary. He would most likely have had some relationship with Lorgalis, which would have turned into "inside knowledge" he could exploit to deceive the Loremasters.
Bandur pretended to be a humble scholar dedicated to fighting the forces of evil in order to gain access to very rare repositories of ancient knowledge. He was the world expert on the "servants of the Shadow", the former followers of Kadaena who were wielding demonic armies in the Wars of Dominion. He was recognized by the Loremasters for this work at the College of Karilon.
While The Legend of the Necropolis of Etrevion explains much of his backstory, many details are left implicit in the various locations associated with him, most notably The Graveyard. His brother Kestrel Etrevion was awarded the Coastal Cliffs area as a fiefdom, which Bandur eventually usurped to pay homage to his own warped theology. Lorgalis would have conquered the whole region in 6521 Second Era. These events originally took place roughly six thousand years ago, but have no official timing in post-ICE Age history. However, Bandur is frequently referenced by players, often treated as a role model for sorcerers.
