For some odd reason, I can see this happening--rather than just the light of day, a giant burning mass that will burn all of Equestria. What would cause Celestia to snap? What if--just what if--Celestia DOES finally snap like Luna? Plus, look at the fandom! Even though Celestia was always depicted as the "perfect pony" and "perfect" ruler, even somepony like her has to have a "dark side" to make her believable. That's the thing about Luna--Luna has flaws, but that's what makes Luna relatable! Anyway, I like what you did hereand it's frickin' awesome!
