Instead of getting Spike a birthday present, Twilight finds herself trapped in a closed universe. A fictional universe, she believes, where nothing is real. Mike has a different opinion about that.
A girl with indigo hair landed in my shower in a flash of light, can use magic, and claims she is, or was a pony...and says I'm the crazy one. I promise, I'm not.
Three ponies appear over a new world, yet they can't seem to remember how or why. Twilight, Rainbow, and Cadence try to find out what makes this new world so different from their own.
