Two worlds, two histories. Two stories come undone and then four people are gone. Two scholars meet for endless learning, and peace is what two worlds are yearning.

The first two chapters are background information on the universes this story is set in. Twilight finds a book that teleports her, Spitfire, and Rainbowdash to a strange world named Gaia during a period of tension between humans and the other races.

Meanwhile someone, or something, is sent to fill the void created when they leave.

Set right after the Crystal Empire episodes.
