The Stockwood Scrolls
The Sword Coast stretches along the Sea of Swords from Waterdeep south to the Chionthar River at Baldur’s Gate in the south. The Sword Coast gets its name from the white cliffs that rise up sharply for hundreds of miles of the coastline, from Baldur’s Gate to the south and up to the River Dessarin in the north.
Officially, the coast line north of Waterdeep up to Icewind Dale is not part of the Sword Coast, though most folk simply use the term Sword Coast for this otherwise unnamed stretch of coast line. In official texts it is often called the “Sword Coast North”, the main cities controlling that area being Neverwinter and Luskan.
