The Saga of Night and Day
Telos, the Great Isle, is almost entirely surrounded by small barrier islands known as the Sister Shores. These islands are incredibly varied in size- from small strips of sand to expanses broad enough to contain civilizations. Notably, the Sister Shores hosts the entirety of the known elven empire. Dwarves of the Sister Shores also consider many of the islands home.
The outer islands of the Sister Shores face violent and largely uncharted waters.
