Gowdie
One of the dwarves who came with Gunilla Goodmountain to Ankh-Morpork to set up the first printing press in the city.
When their vampire iconographer Otto Chriek was struck by a craving for blood he begrudgingly gave up his rat fillets ("I paid two pence for them...") so that the vampire would have something else to sink his teeth into other than the neck of Sacharissa Cripslock.
