Thannish Estuary

The Thannish Estuary is the enormous channel between the Indigo Sea and the Sea of Orel.

The massive Estuary serves as the border between the kingdoms of Gwynne and Orel. A ferry service traverses the waterway between the cities of Seaforth and Kholis.

The channel is extremely busy with marine traffic for it is the only route for ships travelling between the Sea of Orel and the Amador River.
