Celestia gets sick and Luna is worried, but then another "Miasam" (link to story here: [link]) comes. It is attracted to Pinkie and her powers (due to the insane and sadness). It absorbs Pinkie leaving her in shadows. NMP starts to do weird things to the sun only making Celestia sicker. Luna tries in her control to fix it but she can't. She calls the leftover Elements asking them for help. One brings up the elements must be harnessed by their children with the help of their friends for their are more elements each one represents. It is up to them to save the world, Celestia, and Pinkie Pie. The fate of Equestria and their world is up to them if it's saved or not.
