Ok if you've given all those people the samples you were suppose to...well ok ,you need a priest outfit btw, you teleport to varrok and go south east to where a guard is guarding the entrance and you go in there, then you go south to the bar (or they're near it) well theres those 3 guys you gave those vails to...well just talk to them and they will give you them back for NO COST AT ALL!
now just take the vails and well go talk to the last person your suppose to talk to (Sorry i dont where exactly just head north east and you will find someone...well just talk to him and give him the vails)
MAKE SURE YOU HAVE THE PRIEST OUTFIT ON OR IT WILL NOT WORK!
