Gaz was a former fisherman from Darujhistan who lost his fingers when his net was torn away, leaving only his thumbs. Embittered, he turned to drinking and fighting, and ultimately to murder. He was married to Thordy and lived in a poor stretch of the Gadrobi District.
In Toll the Hounds
Gaz unwittingly helped his wife's ritual to fuel Hood's manifestation in Darujhistan by collecting the lives of those he killed. Thordy killed him as the final step in the ritual.[1]
