After Koboh's moon was struck by an Emergence during the Great Hyperspace Disaster of 232 BBY, large fragments of the moon pummeled the surface of Koboh, damaging part of the manse. This rendered some of its passageways inaccessible and made gaping holes in some of the walls.
Centuries later, in 9 BBY, Jedi Knight Cal Kestis discovered a broken Abyss compass on a desk in the Central Manse, and saw through psychometry how when Jedi Knight Dagan Gera fell to the dark side of the Force, two Jedi decided to destroy the Abyss compass to prevent Gera from acquiring it. Gera quickly killed the two Jedi in his frustration. Kestis brought the Abyss compass with him on his travels as he sought the way to Tanalorr.
