The powers of heaven and hell are in constant conflict. A great and final battle looms on the horizon between the dualistic forces of the universe. The armies of good are numerous and powerful, however, the ranks of evil will always be more plentiful and defeat seems to be the foreseeable outcome for the angels of Heaven. The last hope for heavenly forces, a pony by the name of Stone Plow, is discovered in a distant corner of the multiverse on a quaint rock by the name of Equis where the power of magic is derived from friendship. Cassiel, the angel of solitude, is sent to watch over this still young warrior, in hopes that one day he may be powerful enough to repel the forces of the fallen angel of light, Lucifer.
