One of the first cutscenes in
Phantasy Star III introduces Maia, the mysterious bride of Rhys. She was discovered, by Rhys, washed ashore on a beach near Landen. She had no memory of her past. In fact, the events that lead to her presence in Landen remain a mystery to this day, long after the game's release. Considering that each dome of the Alisa III was closed off from the others, there should have been no way for Maia, or her cousin Lyle, to enter the Landen dome.
