Endless War: the bulletpoint mentions that the Watch Fortress is built on a Necron Tomb World, but I don't remember seeing a reference to that anywhere in the fluff from the DW books. Attached to a Xenos Artifact, maybe, and there's the whole Omega Vault to ponder, but I was wondering if anyone had a solid reference to it that I could look up?
