===The Mongoid Ork Wars===

{{Main|The Cleansing of the Mongoid Sector}}

The discovery of the devastated remains of the 8th chapter group, led by Vanheim Paracel of the legion's Sacred Band and lost at the close of the Pulmn Campaign, would lead to one of the most trying campaigns of the Great Crusade. Johannes, under heavy pressure from Captains Salk and Vira, outfitted an expedition to the nearby Renyl System to investigate the cause of the destruction. Salk was given command, but only a limited cadre of veteran soldiers were dispatched alongside himself and Captain Vira. The primarch reasoned that the majority of the legion would better serve the Imperium by continuing their relief work in the Life Bringers' tributary systems, and Paracel was infamous for his mercilessness and disliked by most. The resulting battle would prove to be one of the hardest tests of Vrach's command, and whether he passed or failed this test is a subject of much debate.
