The Serano Ocean was a large ocean that covered the area around the Lesser Islands chain. Apparently several sunken cities lay beneath its surface. After the destruction of the Hollows, several Leviathans and Manglers made their way into the ocean. During the Lambent Pandemic, Lambent Leviathans and Lambent Stalks also lurked in these waters.
