The Cliffs were formed when events at the end of Golden Sun caused a large earthquake and tidal wave, which pushed the continent of Indra southwards and wedged it in between Gondowan and Osenia. The Cliffs can be quite treacherous to navigate, and contain many monsters. Never the less, the Cliffs allow for land travel between the two continents, and allowed the violent warriors of the Kibombo tribe to raid Madra and steal the Black Orb that controlled Piers' Lemurian Ship.
