During the winter of 1267, he went out ice fishing when he was approached by Ciri, who was looking for the fabled tower, Tor Zireael. Initially cautious, Gosta nevertheless confirmed she was near Tarn Mira though it only had some ruins there, no tower. He did, however, draw out a map in the ice for Ciri and gave her directions on which paths to take to get there.
After Ciri took off, Gosta listened to his instincts and quickly packed up and traveled through the forest to get home rather than taking the trail, as he had a feeling the young woman was being pursued. This proved to be accurate, as an hour later Stefan Skellen and his gang came through the area in their attempt to catch Ciri.
