||https://derpibooru.org/tags/chaos+theory+%2528arc%2529|| This arc is about ||Discord converting himself into the Lord of Order, [Accord](/images/1883667) who [acts like someone very familiar that's standing right beside him](/images/1352619).||
This other ||[story](/tags/my+little+pony-colon-+generations) takes place after [Season 10](/search?q=Season+10) and before The Last Problem where Starlight only took a half of the arc doing basically nothing.|| ||Also it's a crossover between g4 and g1||
Every other comic is just her in a cameo.
