During the events of the Changeling attack on Canterlot, Twilight and Cadance's escape did not go unnoticed. An ancient resident of Tartarus, whom for millennia has lain a prisoner beneath Canterlot, has awoken, and merely waited for the right time. With the Demon Kllackra free and upon Equestria, he thrusts the Element Bearers into an almost digital pocket dimension he simply calls The Game. With no other option the Six must battle to escape The Game, but Kllackra is a cruel demon.
