Bore Wars
The Bore Wars were waged in M41 before the forming of the Great Rift.
The war began when the Cult of the Four-Armed Emperor took over the volcano-farming world of Thousandile in a single year. Having been commissioned to "bleed" the lava rivers that threaten the world's Hives, the Cult's Trysst Dynasty was able to bring in hundreds of gigantic industrial drills. Manipulating events to their own ends, in the Day of Eruption all of the geothermic tunnels dug by the drills were deliberately overflowed at once. With the lava swiftly rising, the world's Hive Gangs moved to higher ground, fighting their way into the upper spires and fighting through Spyre Hunters Imperial Guard who attempted to block their path. Meanwhile, the Four-Armed Emperor managed to take more and more of the hive for their own territory. When the lava eventually receded, the Cult used aqua pipes and sluices to harden the metal of the main Hive once more and gain a foothold on the planet.[1]
