History of Xol

Xol, Will of the Thousands, is the weakest of the five Worm Gods that created the Hive. He feared Oryx and allied with Oryx's excommunicated son Nokris, who became his high priest, travelling to Mars. In Destiny 2: Warmind the Guardian defeats Xol with Rasputin's help.

Later in-game lore says Xol “perished but was not destroyed”: it describes death as metamorphosis and says Xol continued to act through the Whisper of the Worm.
