An automton who dwells beneath the Lower 9th District in a water logged wooden maze. In the maze is his workshop where he spends all his days by the light of a single electric lamp. One hour is spent intricately carving stakes and the next trying to remake his shattered left arm. He clearly has had a lot of practice at both but though the walls bear the signs of many thousands stakes a new arm is beyond his reach.
Tock has on the suggestions of mouth ears and eyes but seems to sense and talk as well as anyone.
