Nepto Dragon

A sea dragon that rules the waters around the Nepto Temple in a faraway world. If that world's literature is to be believed, it was once driven to indiscriminate rage by the theft of a jewel from one of its temple statues, sinking more than a few ships that sought passage through its waters. Realizing that its incredible strength made defeating it outright impossible, the Warriors of Light are said to have instead restored the jewel to its rightful place and thus quelled the dragon's fury.
