This seems to be a lot of head canon for people, and I’m alright with this. This animatic video features Discord, Celestia and Luna back in their youth, before the chaos began. The goal of the team behind this is of course full on animation. Full video behind the page break.
Unrelated note, I’ve unlocked the fixed background, it was suggested to me a few weeks back as it seems fixed backgrounds and chrome don’t play nice. It definitely makes it less of an effort to scroll downwards, that is for sure.
