An enchanted island accessible from Skellige. The island is surrounded by shipwrecks and infested by monsters. Otherwise devoid of life there is a lone building on it.
- Strange Cottage
Upon escaping the Wild Hunt on Hindarsfjall, Avallac'h placed a spell on Ciri putting her into a sleep like state and hid her on the Isle shortly before succumbing to his curse and becoming Uma. This was done to protect Ciri from being detected by the Wild Hunt.
When Avallac'h's curse was lifted, he reveals that Ciri is on the Isle to Yennefer and the Witchers of Kaer Morhen. Geralt of Rivia then traveled to the Isle and found Ciri, who awoke upon his arrival. When leaving the island they were discovered by the Wild Hunt, forcing Ciri to use her powers to teleport herself and Geralt to Kaer Morhen.
