Lullabee Island was a island in the center of North Lake in the Free Glades, completely covered with a thick grove of lullabees. A clan of Oakelves lived on the island, and only those with their permission could visit. Rook visited Lullabee Island during the events of Freeglader, and, upon the instructions of the Oakelves, slept in a caterbird cocoon for two weeks.
