Deadalus (pronounced DEAD-uhl-us) is an entity that is said to have created The Labyrinth. No one truly knows who or what Deadalus is.
Many have speculated as to what Deadalus is- some say that he was a diety, others say that it was a highly intelligent species. Many also claim that Deadalus never existed. Some even say that Deadalus is the energy source at the Labyrinth's Core.
(The nature of Deadalus will be revealed in a future Book 3 story)
