Shards of the Shattered Pact: Seowyn's Crossing
The Sea Neverending is an area of the Elemental Chaos, several days travel from the City of Brass. If one sails out of Lake Easifa on the Keysar River, one will eventually come to the mighty cataract of fire known as the Demon’s Curse. This cascades hundreds of feet down into the Sea Neverending.
As its name implies, the Sea Neverending seems to be an infinitely vast expanse of salt water, home to leviathan creatures such as elemental whales and monstrous kraken. It is known to have many other elements in it, including the Stormwrack Isles.
