Origin

Origin is a region in Xenoblade Chronicles 3. It resembles a mechanical sphere, and the first Ferronis. It is the final region in the game.

Story
It is revealed by Queen Nia that Origin is an ark that houses the consciousness of the worlds of Bionis and Mechonis, and Alrest respectively with the intent to reboot them once both worlds fused back into one. Each half of Origin was constructed on each side of the worlds, with the one on Alrest designed by a certain Nopon engineer. Ultimately, the reboot process failed due to Z and Moebius (who are a manifestation of the stored consciousness' fears) interfering, imprisoning Melia within Origin as a means of taking it over.

Since Origin rests beneath the Great Sea, it is impossible to traverse there by normal means, and thus the party requests Samon to use the Bravery (which can traverse the Great Sea). But the ship is incomplete; the party need six Origin shards to complete it. After the party traverse all over Aionios to retrieve the shards to complete the ship, the party and several Lost Numbers stages an assault on Origin, only for Z to activate it defenses. Origin then begins to fire upon the Lost Numbers, the party, and even Colonies that are still bound to Flame Clocks, much to the party's horror. Eventually the party manages to penetrate Origin's defenses and reach the interior.

As the party explores the inner chambers of Origin they came under attack by constructs that comprise of Moebius. Eventually the party reaches the Eternal Prison (where Meila was held prisoner) in which N ambush the party, but was swiftly defeated, prompting N to reunite with Noah before freeing Melia. As the party explores the depths of Origin, they came under attack by a swarm of Kurria Flak (which are repelled by the arrival of and Ghondor), X, and finally Y before finally arriving at the core of Origin which contains an Amphitheater.
