Head to the location indicated on the map (which can be located here) and, once there, play the flute to reveal Zeefzopul. To do this you will need to slay some Imps Once you have slain enough you will be given a map and a Magic Flute.

Once you tell her of the demise of her apprentice, she sends you out to find Zeefzorpul and return a scrap of parchment to her. Return to Grizelda and report your findings. Follow it north until you find a charred corpse (usually past 2 guard outposts) and be very careful to stay on the path. She directs you to the road west of the ruins and up the road towards Yew's graveyard.

You will be sent off looking for one of her apprentices with warnings of the vile Zeefzorpul. The Witch’s Apprentice quest start when you talk to Grizelda The Hag, who can be found in some old ruins out in the middle of the woods far south of Yew.
