The Shackles in the Rocks

Hey guys and here is my new dragon to show.  So his story is that he was a might dragon but was tricked one day and has been put in eternal imprisonment in the very earth he loved.  He gets no meat but only water, for his kind can survive alone on water and he has an immortal soul but the imprisonment is despairing and all he gets to look at of the outside world is what passes by the water hole.
