from the amazing  Ageaus here we see Cove, the Royal Grand Mage Merdragon! (he really was overdue in getting art!)

Here we see him in his own study, a place within the palace where he can conduct many of his mystic arts and research on the mystery of the oceans secrets. It is also a place where he can craft potions to help the sick and cure those affected by dieases. Along with his Royal duties as the Grand Mage for the King and Queen of Poseidon as well as the kingdom, he is also a teacher for Hania, Maku, and Alo in the art of mysticism.
