Odyssa is the county before the Aegaic Ocean. It is bordered by Tristan's Hills in the east, the Ocean in the south and the Silver Run in the north. It is a great hub of trade, with large cities on the Coast of Wonders. The capital Ismarus lies in the ideal location on the east banks of the mouth of the Great River. Many humans call this land home.
The Thera Mountains form a solid spine through the southern landscape. Its tailbone extends into the seaside slopes of Odyssa, where they form a friendly horizon. Here lies Rhûn, a great stronghold that the dwarves have settled in the southern counties.
