Winged Discs were included as mercenary vessels of the Ostense Council in the Tau Empire's Fourth Sphere of Expansion, where they were fitted with Slipstream devices. When they entered the Warp, the fleet's mercenary ships were attacked by Daemons, including the Ostense Council's Winged Discs, Greet Lineships, Human Cruisers and Cutters, Kroot Warspheres, and Nicassar Dhows. The Daemons ripped open the craft, and physically carved the crews apart with weapons, bare hands, and mouths.
