At the very edge of the Iquathan Deeps in the northern Segmentum Ultima, near the border of the Ghoul Stars, sits the sentinel world of Orask. Orask is garrisoned not only by its own feudal, warlike people, a stoic breed who much like the peoples of Cadia or Mordian have long become accustomed to war, but also by many Imperial Guard regiments, and even special detachments of the Adeptus Astartes and Titan Legions rotated through deployment there on a rolling basis. Such a powerful garrison is needed to man its planet-wide network of defences, and along with forces from the Imperial Navy's Battlefleet Ultima, sally forth into the surrounding star systems should the need arise, for Orask is a world where conflict is never far away.
