This occurs during a night where Twilight has Shining Armour babysitting Hestia and Aphrodite, twins born of Discord and Twilight after Discord’s defeat. She goes to visit her imprisoned lover, who’d been turned to stone by Celestia after snapping and taking his insecurities out on Ponyville.
 
This happens before the outbreak of Pinkie, so ponies are more so on the down low and the main six aren’t as frightful and separated, of course though, there is an after effect from Discord.
 
Also I know proportions are inaccurate but I’m doing my best.
 
This universe is supposed to have a focus on Pinkie Pie and her downfall, but does feature a storyline for Twilight.
