Sea Dragons were the first inhabitants of Magnamund. They were demigods loyal to Kai who became mortality in order to secure victory for the cause of Good. They lived in the oceans at the dawn of history. Naar sent False Dragons who mimicked the Sea Dragons' form and corrupted their society. Kai warned Nyxator of the danger who lead the remaining loyal Sea Dragons out of their ocean homes to build Cynx. They eventually lost their war with the False Dragons and were all destroyed with the exception of Nyxator.
