Oulanne was a planet with a single megacontinent. 18 months after the Battle of Yavin a massive earthquake hit the planet, leaving the citizens in despair after the Galactic Empire refused to send aid to the economically unimportant planet. Shortly after the earthquake, the planet was further devastated by a megahurricane that hampered relief efforts. Despite the odds, the crew of the Mighty Oak Apocalypse was able to deliver aid to the southernmost peninsula of the planet's megacontinent. The Rebel Alliance also sent a group with aid, led by Wedge Antilles.
