Sea of Swords

The Sea of Swords was a region of the Trackless Sea that separated the western coast of Faerûn (known as the Sword Coast) from the Nelanther Isles and the Moonshae Isles.

Geography
The major island chains of the Moonshaes and the Nelanther Isles and the jutting Tethyr Peninsula formed a rough boundary for the Sea of Swords. However, various authors have described the Sea of Swords as extending around the peninsula to meet the Purple Cliffs (the western edge of the Purple Hills in Tethyr). On the northern end, at least one author placed the island of Ruathym in the Sea of Swords, and another added the island of Gundarlun and even the Purple Rocks. It was not unusual for the Sea of Swords to be considered extending as far north as Luskan.

Inhabitants
At least one kingdom of sea elves, known as Nindrol, claimed the waters around the island of Toaridge-at-the-Sun's-Setting just north of the Nelanther (or the northernmost island of that group, according to some maps ).
