The Whirlwind Legion was a band of mercenaries serving former Fist Korbolo Dom during the Whirlwind. Before the Fist turned renegade against the Malazan Empire they had been part of his larger Malazan Legion. But half of the original legion refused to join his mutiny, and Korbolo Dom had them executed. The remaining legionnaires "divested the Imperial uniform, proclaimed themselves mercenaries, and took on Korbolo's contract."
