Dragon Ogre Gathering

Dragon Ogre Gathering is a Warriors of Chaos military recruitment building in Total War: Warhammer. No one truly knows when and how Dragon Ogres gather, but they always assemble on ground sacred to their ancient pact.

Background
When the pact was signed, whereby the Dragon Ogres sold their ignoble souls into damnation in exchange for near-immortality, several of their meeting grounds were said to be frozen in time. Marked with a boundary of skulls, these sites are immune to the warping effects of Chaos. Should a Daemon, or any servant of the Chaos Gods bearing their patron's mark, ever step over the skull boundary, then the pact between them will be ended.
