Eryth Sea is an area in Xenoblade Chronicles located on the Bionis' head. Alcamoth and Prison Island are floating above it, as well as many smaller islands.

Geography

Eryth Sea is a large freshwater sea situated behind the Bionis' head and directly above Makna Forest. The sea itself does have a few islands directly on it, however, most islands in the region instead float high above the sea. Furthermore, the sea itself floats through unknown means. In Future Connected, Shulk postulates that the Hovering Reefs were made to hover by the Giants using Hover Stone found within the Bionis' Shoulder, though the truth of this is inconclusive. The islands themselves are largely identical in climate to one another, as well as the shores of the sea. Terrestrial plant life strongly resembling various types of oceanic life can be found growing on shore and island alike, alongside yellow grass. The whole of the region is enclosed by the Bionis' back fins, which seem broadly verdant and forested when viewed from above.

As center of their civilization, the High Entia have built many structures on the sea and its islands. Chief among these is Alcamoth, the massive floating capital city on the east end of the sea, accessible through a network of transporters linking the floating islands. Additional High Entia infrastructure such as the Ether Plant and Syrath Lighthouse can be found on other islands. On the opposite end of the sea is Prison Island, a large black tower different in size and structure to the other islands on Eryth Sea. The transporter to this island has been sealed by two additional islands.

Story

Taking the transporter from Frontier Village, the party arrives in Eryth Sea. As they require official sanction from the High Entia emperor to enter Prison Island, Melia guides the party to the High Entia capital Alcamoth to both request permission and report the successful slaying of the Telethia in Makna Forest. She leaves the party outside the city, though they are subsequently taken into custody.

Following Melia's successful completion of the Trial of the Tomb, the Mechon attack Eryth Sea. Emperor Sorean heads to Prison Island, unsealing the imprisoned giant and ancient creatures within to fend them off. Knowing is to be killed by Mechon, the party follows after him to try and save him. They undo the seals and enter the island.

After Zanza is awakened, he prepares for the destruction and recreation of all life on Bionis by sinking Prison Island into the head and transforming the pure-blooded High Entia in Alcamoth into Telethia.
