During the Horus Heresy, the region was heavily infested by Orks and was chosen by the treacherous Warmaster Horus as the location to dispatch Jaghatai Khan and his White Scars. Due to its layout, it would take The Khan a lifetime of fighting to clear the System of Orks while he could could meanwhile initiate his rebellion against the Emperor.
