Outer Sea

The Encircling Sea of the World

Map of the Outer Sea
Arda and the Outer Sea (somewhat conjectural)

The mighty sea that surrounded all the lands of Arda, Middle-earth and Aman alike. Its dark waters lapped the western shores of Valinor, and at its distant unknown edge stood the Walls of Night. Ulmo's halls were within the Outer Sea, and it is said that mortal Men made their last journey across this frigid ocean.
