Falkus Kibre

Falkus Kibre, the Widowmaker, led Justaerin Terminators under Abaddon and stood at Horus's shoulder through Isstvan, Molech, and the long sulk after Russ broke the Warmaster. He was never Mournival. He did not need to be. The Justaerin were the argument that first company work is done in cataphractii, not in a four-man philosophy club.

After the Siege he hunted Abaddon through the Eye with Khayon and Lheor rather than sit Maeleum's ruin and pretend Horus was coming back. When the First Captain returned, Kibre was already in the inner circle of what became the Black Legion, still running Terminators, still answering to a man who refused to be another Lupercal.

The Bringers of Despair are the Justaerin with the serial numbers filed off. Kibre is the continuity. Cthonia made him a killer. Abaddon made him a habit. He is still both.
