the basic concept of this AU is that (most) major protagonist roles are swapped with characters which are antagonists originally, whether just episode antagonists or outright villains
Discordant “Discord” Rain, a pegasus with a penchant for throwing particularly wild and chaotic parties, is the Element of Inspiration in this AU–the analogue for the Element of Laughter. The way Discord sees it, it’s not worth it if somepony doesn’t get to laugh about it. He uses a blend of pegasus magic and chaos-tinged party pony magic to spruce up the events he throws from time to time — which is where he got his cutie mark (which depicts a chocolate raincloud) from.
(the elements of harmony i made for these are all just basic gem shapes, as the universe here ‘isn’t right’… so as a sort of hint to that, the Elements don’t form into the ‘destined’ cutie mark shapes, because they were never meant to be wielded by these 6)
