More commonly known as The Twilight Sea, Stallynmere lies between Tarnberyth and Jotunland. It contains the great island nations of Pendaran and Saith as well as the old elven nations of Kathillion, Sarthillion and Venthillion.

To the south-west, the Stallynmere is bordered by a long chain of islands, called the Elven Isles, that stretches from the Ivory Coast to Jotunland. Once home to the great elven nations of Kathillion and Venthillion, it is now the haunt of pirates, giants, Saith raiders and other renegades.

Stallynmere is one of the busiest seas on Gwelith with abundant trade between the Ivory Coast, Kaylonna and Tarnberyth.
