Equestria's heroes are missing, and so are almost everypony else. Twilight must get together 6 new Elements to defeat the strongest foe they have ever seen. And biggest. Definitely biggest. But, however, is Princess Celestia right about these new "heroes"? Are they able to defeat this foe? Twilight doesn't think so. (There also more main characters, but I don't have enough slots for them.)
