Hybras
Hybras is an island featured in Artemis Fowl: The Lost Colony. It is a lunar rock of considerable size which was disconnected from the moon when it was hit by a large meteorite. Upon landing on Earth, it was met with a magma stream and was welded to the surface. The demons and imps which live there are descended from bacterial life forms in the lunar soil. During the "Battle of Taillte", warlocks of the demon tribe transported Hybras through a "time tunnel", arriving in Limbo, where time does not exist. In the fifth book, the time spell starts to unravel. Following Artemis' help, Hybras is moved back to Earth.
