Pebble Bay is a large body of water that stretches from Starry Point to Blackrock Mountain. Its waters are located in the westernmost region of the Frontier. Pebble Bay borders two other major bodies of waters, those being The Far Coast at its southwestern point, and the The Long Coast (Frigid Waste's coastlines) at its northwestern point.
The overall geography of the coastline can be summarized as a coastline littered with large boulders and small undergrowth, hence its name. The only notable landmark that exists within the territories of the bay is a small, wooden dock, battered by the tides and weather.
Birds that can be found in Pebble Bay include Beachbird and Gull.
