Larkin was a soldier of the Malazan Empire who had fought in the Genabackan Campaign. He was stationed in the garrison on Malaz Island. He was a young braggart who liked to spin tales to make himself sound braver than he was. For example, in one of his tales, he said that his leg wound was the result of a clash with the Crimson Guardsman, Lazar.
He had small eyes hidden in a wide face.
Larkin had an adversarial relationship with fellow garrison soldier Temper. He belittled the old veteran in front of the younger soldiers in an attempt to puff himself up, never realizing the man was once one of Dassem's First Sword.
