In a bid to gain popularity and show off her power, Trixie Lulamoon has unleashed the power of the Chaos Grimoire. As a result, she summoned Balrog, a demon from another realm. With a powerful creature at her disposal, she had managed to corrupt most of Equestria and started a blood sport to maintain her place. Even the bearers of the Elements of Harmony can do little more than try to control the damage Balrog's corruption is causing.

Three years later, Lyra Heartstrings has fallen into debt, and was forced to sign up for the tournament to raise money. Of all things, she summons a human from Athelina, the same realm as Balrog. Although brought into Equestria against his will, Miles Skylark swears his loyalty to Lyra, and with the help of Twilight Sparkle, takes a stand against Trixie and Balrog.
