The Eryth Sea (English dub: /ˈerɪθ/) (エルト海, erutokai) is a great sea located on the head of Bionis in Xenoblade Chronicles. Floating islands are connected by transporters. Shulk and his friends arrive here in search of the tower from Shulk's vision. Later in the game, the Eryth Sea becomes filled with Telethia.

Story

This sea is the home of the High Entia. The sky seen in Makna Forest is the sea itself. From time to time, part of the water reaches Valak Mountain, which is the reason of the relentless blizzards of the region. This area is known for its apparent meteor showers, which are actually condensed Ether falling from the sky. The High Entia capital, Alcamoth, lies suspended above the sea.

The sea can be reached by use of a transport from the top of Frontier Village (but conversely Frontier Village is not accessible). After reaching Eryth Sea, Melia leads the party through several transporters and isles, until finally arriving at the capital's transporter. There, they are received by a group of High Entia soldiers who greet Melia, and call her "Lady", which confuses the party.

After the reawakening of Bionis, a group of fleeing High Entia uses the Ether Plant and the Syrath Lighthouse as refuges.
