The large inlet known as Aspo Bay lies along the coastlines of southwestern Andoran and southeastern Cheliax on the Inner Sea. Both the Andoren towns of Augustana and Chimera Cove and the Chelish city of Ostenso are built along it. Aspo Bay is also home to countless small fishing villages, along with the ruins of many small Chelish naval bases, which dot its western islands and crags. The most well-known of these is Selian's Watch.
