Jace's home of Ravinca is destroying itself. The guilds are at war with one another over a small piece to an ancient puzzle hidden within the Dragon's Maze. None of the guilds have the piece, and Jace knows this, yet the Guild Leaders won't even acknowledge his requests for presence. He then decides to pursue the piece on his own, finding it in the hands of a human Pyromancer, named Chandra. After stealing it from her, she pursues him across a variety of planes. Jace then makes a fatal mistake, causing him to rift to a realm no planeswalker has ever come across: Equestria.
