It sounds AWESOME!!!! For the main plot, you should have a goal for the main character. Like defeating a bad guy, or trying to achieve something. Example: Ghostspeaker is trying to defeat his mortal enemy Dragonhater and stay away from the dragons in the process, because he's scared of other dragons . While he is on this quest he meets another dragon, and learns that they aren't so scary after all. Meanwhile Dragonhater is coming up with a plan to eliminate dragons forever.
So far that's all I've come up with so far, but let me know if you need more inspiration.
I wish you the best of luck!!!
