The Sentinel Sea is a deep, fresh-water inland sea in the north east of the continent of Arland.
The Sentinel Sea is connected to the Sea of Shards through a rather indirect route of rivers and such. Specifically, the Sentinel Sea passes through the River Arno to the Dragonmere Lake . From the Dragonmere it connects to the Black River, passes through the Pillars of the Titans to the March Sea and eventually will reach the Sea of Shards.

This incredibly long waterway is one of, if not the longest waterways within Arland. A river cog would take over a month's travel to spand the distance from one end to the other. Additionally, rivers that connect to the western shore of the Sentinel Sea permit travel further west though there are no greater bodies of water beyond the Sentinel Sea which are connected.
The Sentinel Sea is the homeland of the human race within Arland.
