We all know what’s been going on with the Main 6 and Tempest while they were away from Equestria. But, the biggest questions would be: What happened while they were gone? What could the Storm King have done while he took up residence in Equestria?
The Order-naries arrive a little too late to take part in the main plot of the MLP Movie. Saving Cadance from the Storm King and making a run for the Crystal Empire by train should make for a fine substitute adventure, though.
