This island was a place of kombat during the conflict with the Dragon King, where the setting switched from night to day and back again ever few seconds.
This island was stuck in-between two realms, Earthrealm and Outworld. Sailors said they had seen an island in a bed of fog, then it would vanish. They said trees would become snakes then turn back into trees again. No one would believe them and blamed the delusions on the rum.
