Against the ZergEdit
The Vanguard of Aiur defended Aiur shortly after the zerg reached the planet. A task force drawn from the Akilae, Auriga and Velari defended a large Khaydarin crystal formation but failed to keep the Zerg from acquiring a crystal.
Protoss Civil WarEdit
During the civil war, the Vanguard of Aiur defended the Heart of the Conclave from Tassadar, Fenix and the Dark Templar. This detachment drew from the Auriga and Ara Tribes. The Heart of the Conclave was destroyed, but this resulted in Tassadar's capture.
