Means 'Sea Home'.

Eämbar was a ship built by Aldarion, the Mariner King, to be his home. This ship was also the guildhouse of a team of explorers called the Venturers. They kept all the records of their travels there.

It was originally moored in the Bay of Rómenna, but it was later moved to Andúnië. It was eventually confiscated by the kings, and all the records on it were lost.
