Starfall Basin is a landmark in Xenoblade Chronicles X. It is located in Primordia, at the southwesternmost part of the continent. During the prologue, Elma discovers Cross in a cryogenic stasis pod here before handing them a Proto Assault Rifle and taking them back to New Los Angeles. If it is visited later in the game, there is a mix of low and higher levelled enemies.
