Sergeant William (Bill) Troyden
Human Sergeant in the Alliance army’s ranks of human infantry.
An expert fighter, particularly with an axe, he tought Stout everything she ever knew, except the stuff she knew already.
A bit like Vimes when he’s pretending to be Sergeant Keel in ‘Nightwatch’. Except when he’s drunk, cos Bill quite likes being drunk, and doesn’t get all down about it like Vimes does.
