The barrier is finally closed, humans are no more and every sentient species is under the government of her majesty the Princess. But somewhere else, other beings beyond time and space have been seeing her acts and now they are ready to judge her.

When a stranger appears in front of Celestia to tell her about the trials against her, everything will change. Beyond good, beyond evil, a judgement will fall and justice will be done.
