Megan, Champion of Dream Castle

So not long after the episode Sleepless in Ponyville aired and we found out that Princess Luna watches over the dreams of ponies i got this idea that was inspired partly by that and partly by the pilot episode of G1 My Little Pony, Escape from Midnight Castle. I made Dream Castle and Midnight Castle both places within the dream world that only Luna can travel to, or so she thought. Tirek was once a creature of Equestria (whether he was a pony or something else no one knows) but when he discovered a way to travel to the dream world he finds Midnight Castle and is claimed by the Forces of Nightmare much like Luna was. After a brief time wreaking havoc on Equestria, Tirek mysteriously vanished for ages. Upon his return, Luna travels to Dream Castle and consults with the Dream Masters (the opposites of the Forces of Nightmare) who them pull a champion from another world to wield their power against Tirek. That champion was Megan.

So here we have her, all decked out in fancy armor (designed by Rarity, the only pony brave enough to try and design around strange, new anatomy) and wielding an awesome sword forged by Celestia and Luna's magic which Megan can use to harness the power given to her by the Dream Masters. There's way more to the story but I'll leave it there for now.
