Osenia Cliffs

The Osenia Cliffs are a series of ridges, rocky reefs, and outcrops that jut from the channel of sea between Indra and Osenia, at it's narrowest point. To the west of the cliffs is the Madra Drawbridge and Madra in Indra, and to the east is the entrance to the Yampi Desert in Osenia. The Osenia Cliffs were created when events at the end of Golden Sun caused a huge earthquake and tidal wave, which pushed the continent of Indra southwards, wedging it between the continents of Gondowan and Osenia. The Osenia Cliffs are the eastern counterpart to the Gondowan Cliffs, but are much less difficult to make one's way through than the latter, and contain no monster encounters or random battles.
