Tethmos

Tethmos is an ancient whose origin predates recorded history during the Heroic era. It was once home to the Therosians who inhabited the Teros archipelago.
During The Great Flood, the city was drowned with the rest of the world and from then on, belonged to the sea. 
At some point in the Second Era, the ruins were colonized by sea elves who took the opportunity to spread their culture to new watery frontiers.
