The future doesn't belong to you!

For those who have not completed games in the Xenoblade Chronicles series, this page contains spoilers regarding the plot. Discretion is advised.


Erythia Sea (Japanese: エルティア海, Erutia-kai) is an Area in Xenoblade Chronicles 3, located in the Cadensia Region. The remnants of Eryth Sea, the Leftherian Archipelago, and Spirit Crucible Elpys make up these seas. It is a body of water located on a massive shelf of land cantilevered above an also-massive void of air above the world's ocean; the sea's water isn't bounded at the edges of the shelf, and flows over the edge as enormous waterfalls.

Colony Mu, Colony 15, and the Lost Colony are located here. Agnus Castle is located above the Agnus Castle Barbican in the northern section of the seas, which used to be the location of the first City at Hope's Rest. After the City leaves the Great Sword's Hilt, it relocates to the massive void of air directly beneath the Erythia Sea's bedrock, but is otherwise a completely separate area map.

In order to traverse these seas at a faster speed, the party can use the Boundary/Bravery to sail throughout the area. Erythia Sea is the largest area of Aionios.
