"Most of the undead dwell in the tombs, but some of them are very powerful. There are however several small squads of skeletons that have been patrolling the paths. You probably have met some already. There is a bunch on this path and they should be by in a few minutes. The zombie master also has some zombies working in the mortuary and there is a small tribe of ghouls in the north east corner of the cemetery, you can't miss their holes if you look."
