The Leftherian Archipelago also called Leftheria is a nation in Xenoblade Chronicles 2. It is a series of medium sized Titans linked together by bridges and tunnels over and under the Cloud Sea. The main settlement, Fonsett Village was founded by the Tornan hero, Addam Origo, 500 years before the event of the game. It is also the resting place of the Pneuma's true sword which can only be accessed by a Leftherian. It is the village in which Rex grew up but since he is able to open the doors with Addam's crest it also means that his parent had Leftherian blood.
