The Oracles of Change is a warband of Chaos Space Marines who were originally the Loyalist Chapter known as the Lectors of Ixis but are now dedicated to the service of Tzeentch after having been corrupted during the Abyssal Crusade in the 37th Millennium. The Oracles are lead by the Chaos Sorcerer Amadeus Volkstein, who was once a Loyalist Librarian Epistolary known as Vanneus before being corrupted by the promise of knowledge and power offered by the Lord of Change. Some have suspected the Oracles of Change of being a splinter group from the Thousand Sons Traitor Legion, though this is largely seen as rumour.
