In life, Orpheon Katakros never lost. He was a general of such totality that enemy nations surrendered on the news of his appointment, a mind that treated war as a solved problem the rest of the world had simply failed to read. Only death itself ever defeated him — and Nagash, recognizing craftsmanship, refused to let so perfect an instrument rot. The Great Necromancer set Katakros's soul aside like a smith setting aside flawless steel, against the day he would have an army worthy of it.
That day came with the Ossiarch legions. Remade as the Mortarch of the Necropolis, Katakros commands the Bonereapers not from a warhorse but from a moving court of attendant constructs — scribes, heralds, and counselors who translate his will into the simultaneous motion of a hundred thousand warriors. He does not fight battles so much as administer them: supply lines strangled a season in advance, fortresses rendered irrelevant by roads built in the night, surrender terms drafted before the enemy knows there is a war. Even the dominions of the Everchosen have felt his legions' tread and been forced to take the Ossiarch advance seriously.
Katakros keeps a ledger of every engagement he has ever commanded, and in all its pages only one entry stands in the column of defeats: his own death. He intends the record to stay that way for eternity — and eternity, for the first time in history, is actually on the general's side.
