Breaking of the Illithids

Revolution

The emipre of the illithids or mind flayers is destroyed by two gith heros

The illithid empire breaks up after the rebellion of Gith and Zerthimon. The Pronouncement of Two Skies follows soon after, when Gith turns against Zerthimon over a difference of opinion on what to do with their emancipated followers. Zerthimon is slain in the battle, and the former slaves divide in two; those that followed Gith become planar nomads, while those that followed Zerthimon establish themselves in the plane of Limbo, eventually becoming known as the githzerai. The gith pirates of wildspace form at some point around this time, but the details of that subspecies's formation are unknown.
