The Oblivion Sea is a large body of water that washes the whole of the eastern coast of Thundermarch.

It reaches far into the east, well beyond the charts of maps. A few islands close to the mainland are populated, and numerous more are further away and independent. People believe that beyond those horizons there is only emptiness and doom, and not a single expedition dared brave its mysteries as of yet.
