First Archon

From Wikipedia of the Dark Jedi Brotherhood, an online Star Wars Club

First Archon was a former position within the Chamber of Justice. The First Archon was the senior member of the Archons (judges) and acted as Justicar during his absence. The position of First Archon was held by only one member, Chi-Long. When the positions of Archons were dissolved, so was the First Archon.
