Great P365 War

"With Equestria left in ruins, it seems that friendship and optimism isn't fading out just yet. We must defend Equestria and Canterlot City so we can put an end to another era of disharmony and darkness once and for all, and for Celestia's sake, we can't hold these evildoers off without any required assistance, even when it's Pika's fault."

--Su Ji-Hoon, The P365 Returns
