Filgakk Skullsplitta and his Blitzdreg Boyz made planetfall during one of the frequent meteor storms that punish the interior of the northern continent of
Xhorik Prime. After contact was lost with several outlying mining and drilling operational posts, the planetary government of Xhorik Prime assumed it was the usual raids of feral orks and abhuman scavengers that have plagued the interior of the planet since the climate-changing destruction of the ork rok in close orbit at the end of the
Second Xhorik War many years ago. The planetary government dispatched patrols of the Planetary Defense Force (PDF) and also requested assistance from the small, permanent garrison of
Red Brotherhood space marines due to their superior mobility and response speed. The Imperium designates Xhorik Prime as a Level II planet of significant strategic importance due to abundant mineral and gas deposits, most notably the rare kleinhaurker ore, which can be refined and combined with other rare metals to create some of the strongest and most durable alloys known to the Imperium. The destruction of the rok left the planet with a low atmosphere of radioactive storms that was impenetrable to surveillance from space or high altitude and garbled most long-distance communication, making scouting operations a requirement for any reliable information.
