When Luna goes off the deep end and turns into Nightmare Moon to plunge Equestria into eternal night, it's up to Discord to stop her. Plus, he's really bored. It seems Nightmare Moon is in some sort of heat. Discord has no idea what that means, but he'll try his best to cool her off.

The poor, poor fool.

Thanks to my prereader Skeeter The Lurker and editor Merc the Jerk for all their help!
