Location: Tranch, Adrantis sub, Calisis Sector

Situtation: A mutant uprising in the soot warrens of the minor (by Imperial standards, by Calixian standards Tranch was an important world) industrialised hive world of Tranch rapidly develops into a planet-wide insurrections which topples the ruling class, the brutal Oligarchs of Tranch. The mutants have formed together into a unified faction calling itself the Pale Throng, led by a cabal of terrifyingly powerful witches and mutant-psykers known as the Shroud Council. As rumours of the successful rebellion spread, so do brushfire revolts and uprisings on other worlds in the sector, and the flames of malcontent are fanned. Lord Sector Hax realises the wider threat to Imperial order and declares a mass counter-invasion of the war-torn world to bring the rebellion to heel, calling on the Inquisition to dispose of the Shroud council, which they do, whilst Ordo Hereticus launches Operation Bellerophon to decapitate the mutant forces. At huge cost in lives and at the price of laying waste to much of Tranch, the Pale Throng is crushed, but its many factions manage to scatter off-world, while sympathisers still raise revolt in the pale Throngs name elsewhere.
