From Origins:
Lord Hark called a conclave at Gnshal Oblitia, a world on the very edge of the sector. Towering in his black and gold power armour and crimson cloak, and reciting baleful stanzas from his Book of Ashes, he demanded action. A bitter exchange erupted in the hallowed vaults of the Oblitia Cathedra ... Centuries of accumulated ill-will, anger, and virulent mistrust amongst the Inquisitors operating in Askellon seemed to quickly boil over to impossible levels. Hark finally ... declared to the assembled Inquisitors that he would have the truth, one way or the other, and with or without the blessings of those opposed to his direction.
