Sergeant Atelen Tinsmith was the leader of the Unta Harbour Guard. He was described as an older man having brown eyes, a long dour face, and a white moustache which hung to either of side of his turned-down mouth which was framed by deep fissures. As a younger man he fought for the Malazan Marines in Genabackis. At some point he served with former Malazan Admiral Cartharon Crust, who reminisced about the times he disciplined "Smithy" with the crack of a belaying pin to the head. Tinsmith wore a leather vest over his shirt and carried a pair of long-knives on his belt.
