Peer over your map of Skellige and locate the island Ciri had pinpointed as the place where Avallac’h’s laboratory is said to be. It is westward, between Undvik (to the south) and Spikeroog (to the northeast). Set sail for this uninhabited pair of rocks (or swim there if you’re a maniac), and locate the cave entrance in the center of the land mass, between the two islands.

Yennefer and Ciri are just beyond the entrance, attempting to open the door sealed with complicated magic. Yen’s attempt to enter succeeds, but activates one of the lumbering golems which must be defeated. You have Ciri’s help with this task. Follow Yennefer into the laboratory, where you all inspect a number of sketches of Ciri strewn on a desk. Ciri brushes off Yen’s comments about Avallac’h being interested in more than just Ciri’s magic abilities.
