Bjorn the Fell-Handed - First of the Lone Wolves: During the Horus Heresy, Bjorn was a young warrior of great potential. He had excelled during the campaign known as the Battle of Prospero and Bjorn's saga was already being crafted by the skalds. He had been there when he was confronted by the Horus-Daemon and heard the words of mystery spoken by the fell creature. His stock had risen, and he was being spoken of as if some deep wyrd had attached itself to him. Indeed, Bjorn's pack (squad) was often singled out to lead assaults where enemy resistance was expected to be at its heaviest.It was whilst undertaking one such attack on the acrid, volcanic world of Gryth that events were to take a tragic turn. Bjorn's pack had humbled tyrants, butchered aliens beyond counting, and even hewn down their brother Space Marines who had fallen from the Emperor's grace; yet against the Daemon king, Arvax the Arch-slaughterer, they knew only death. That Bjorn actually survived the massacre of his kinsmen was a testament to his exceptional skills as a warrior, for all others who faced the mighty Daemon of Khorne that fateful day joined Bjorn's packmates in death. Though the arrival of the mighty Primarch Leman Russ saw the Space Wolves ultimately emerge victorious against the daemonic warhost, it was Bjorn's relentless assault who finally drove the seemingly unstoppable Daemon general from the field.Despite his victory of sorts, Bjorn never forgave himself for the loss of his kinsmen, nor the fact that he alone yet lived, having been denied a magnificent death. In the hours that followed the battle, Bjorn became increasingly melancholic, refusing to accept the hearty approval of those who had witnessed his heroic battle against the Daemon king. As he witnessed his packmates burn atop the victory pyres, he gave voice to a long, mournful howl. Kneeling before the bodies of his burning kinsmen, he swore a grave oath of vengeance against their slayer.To Bjorn's continued frustration, it was to be five long standard years before word of Arvax's location surfaced once more. Russ immediately led his Space Wolves to destroy the foul creature, determined to personally slay the Daemon king himself and avenge those who had died during their last encounter. Yet in this goal, the primarch was to be denied, for Bjorn too sought out his nemesis and, as fate would have it, was the first to face Arvax in battle.As the Wolf-King tore through the Khornate horde towards his quarry, he witnessed Bjorn's duel first-hand. Russ could only look on in pride as Bjorn deftly rolled beneath a blow attempting to cut him in half, then clambered up the Daemon's towering frame to tear out the Arch-slaughterer's throat with his trusty Wolf Claw. In the aftermath of the battle, Russ came to Bjorn in person and exonerated him in front of the entire Legion, holding his oath fulfilled.Setting a precedent that still exists to this day, the Wolf-King promoted Bjorn to his personal Wolf Guard, naming him the "Fell-Handed" in honour of his mighty deed. The Skjalds of the Chapter hold that it was the sense of loss and tragedy that Bjorn had already experienced and learned to master that influenced Russ' decision to leave him behind when he set forth on his last, fateful journey into the Eye of Terror. Of all of the primarch's Wolf Guard, he alone had shown such strength of purpose and determination in his darkest hour; he alone would understand the lonely burden of command in the primarch's absence.
