Royan Island is a small, private island located twenty miles off the coast of California. It was originally owned by a bootlegger named Royan back in the 1920s and was later purchased by a family named Marquez. Royan Island was used by the Yeerks in The Escape, where they built a secret underwater base, which was used to oversee a project to use modified hammerhead sharks for infestation, so that they could be used to invade the planet Leera, but the project was terminated when the base was destroyed due to the Animorphs's interference.
