Paltna

Like

One of three oceans on Annora, it is the smallest ocean. Scientists currently do not know how it relates to landmasses on Annora or Annoraann, or even Sofeä, but they do understand that there is a certain amount of water within the confines of Annoraann that is responsible for the amount of moisture present in the atmosphere. 

Such amount varies between 445 million and 700 million cubic kilometers of water. If the upper estimate is correct, then it would be larger than Pontus.
