Sea of Sharks
The Sea of Sharks is the most northern sea in Earador. It is known to be the home of Aquaycia and the Umizu who dwell within. Not many ships travel on the sea and the closest settlement on land is Moon River. This settlement often has to deal with raids by Umizu but fortunately not as many.
Settlers of the Northern Hills have considered that there may be another enemy of the Umizu who dwells in the sea which causes the Umizu to not focus on raiding as much. So far that has not been corroborated.
Geography
It is a very deep sea, with many underground mountains and volcanos.
