Cremlevian War

The Cremlevian War was a conflict that occured thousands of years ago in the Yuuzhan Vong galaxy. It was fought to unify the Yuuzhan Vong into a single socio-political entity.

During the end of the war, Steng served as the first Warmaster. The rival Warmaster, Yo'gand, developed the Yo'gand's Core tactic, which he used to destroy the planet Ygziir and its moon. The destruction of Ygziir resulted in the death of Steng, the end of the war, and unity of the Yuuzhan Vong people. As a result, Yo'gand united the clans and became the first Supreme Overlord of the Yuuzhan Vong. However, their galaxy was ruined, and the Yuuzhan Vong began the trek to another galaxy.
