Ha ha, don't worry! I've got enough story planned out for this to last many, many years.
Kelzar Mage was really all about that one scene, which originally was going to be the opening for DA2 (was planning to do a cut-scene thing). After that, I really had no idea where to go next and the next scene I had planned didn't sit well with me. DA2 is a finished story, so figured it was best to leave it be.
