Fort Excalibris is a Deathwatch Watch Fortress that is located in the Segmentum Obscurus. In late M41 its Kill-Teams were stretched to the breaking point, as they dealt with multiple ongoing Xenos threats. This included the Dark Eldar redoubling their attacks around the Crucible of Tales, the Necrons of Icnarus push towards the Gothic Sector, and the Hrud infestations discovered throughout the Kuypax Reach.
