The base of this plot is simple; after Avan has a recurring nightmare, he wakes up to find a problem; his magic cut off. With no magic, it means that one of his spells; the spell that he uses to understand everypony, is out. With unable to talk to anypony or understand, can they figure out what happened and how to fix his magic? Will this force Avan to face something from his past that he never admitted too?
I came up with this plot when I realized that Avan most likely never bothered to learn Equestrian because he used a spell to understand it when he first came to Equestria. Realizing this, I saw how fun it would be to have him lose that one way of talking and having to figure it out. I still have no idea what exactly caused his magic to cut off, but I have a feeling it has something to do with the nightmare. I have no plans of doing this plot anytime soon through, and I am really just putting it here so you guys know about it...And I will have something to look at when it comes around to it.
