The Forgotten Sea is the endless expanse of ocean that stretches beyond the Cerulean Gulf. This is the indisputable domain of Sydon, the Lord of Storms. The sailors of The Kingdom of Mytros and The Kingdom of Aresia know better than to cross through the narrow straits of the Barrier Islands, because the Titan does not suffer trespassers to live. Death awaits any mortal who ventures into the territory of the ocean god.

There are hundreds of islands in the Forgotten Sea.
