|Island of Kail|
Unknown corner of the seas
The island's location is unknown to most of Earth's population and it's very existence is considered a myth. Only few people like Agenor know how to locate it and to even get to the island the person who wants to go to it must use Poseidon's Trident to make the island visible to the human eye (tough only Agenor and Poseidon are the only ones who can use the Trident for such specific purposes).
- Another island inhabited by Cyclopes appears in the comic book Wrath of the Titans: Cyclops. The island is called the Island of Colossa.
