Y'Berion is the founding guru of the Brotherhood of the Sleeper and the leader of the Swamp Camp. He was the first inhabitant of the Colony to make contact with The Sleeper through dreams, and he led his followers into the southern swamps to build the camp around that revelation. He is referenced in backstory dialogue in the Nyras Prologue demo, which grounds the Brotherhood's existence in the remake's world before Nyras even meets anyone from the camp.
The Brotherhood
Y'Berion leads the Brotherhood of the Sleeper as a religious order rather than a mercantile or rebel faction. His followers believe that fully awakening the Sleeper will break the Barrier and free them all. Y'Berion receives the Sleeper's communications on behalf of the camp and translates them into directives for the other gurus and followers.
Hierarchy Beneath Him
Directly beneath Y'Berion sits his deputy Cor Kalom, who runs ritual and drug-alchemy operations. Beneath Cor Kalom sit the Templars, the Brotherhood's armed wing, led by Cor Angar. Lester is one of the Brotherhood's low-rank novices and the first Swamp Camp contact a Hero following the swamp path is likely to meet.
Relationship to the Hero
A Hero who joins the Swamp Camp meets Y'Berion early in the admission arc. He is the authority who formally welcomes the Hero into the Brotherhood and directs him toward the rituals and tasks that matter to the cult. Even Heroes who do not join the Swamp Camp cross paths with Y'Berion during the artifact arc, because the Brotherhood's interest in the Focus Stones ties them into the main story.
