 Dr Hix is a necromancer.Since necromancy is officially banned in Ankh-Morpork, he is instead the Head of the Department of Post Mortem Communications (although he acknowledges this is just a fancy way of saying necromancy).Dr Hix has one member of staff, a reanimated skeleton called Charlie, who helps procure the tools of the trade (which are mostly items from the joke shop down the road).
