Nistola held the position of Imperial governor on the planet Basilisk in the immediate years after the Battle of Endor. Following the invasion of Basilisk by the New Republic, Nistola yielded to the invading forces. This surrender occurred after the Katarn Commandos successfully breached his well-defended aerial stronghold. Subsequently, General Garret of the New Republic was able to deploy his troops and seize the capital city without any combat.
