When Rainbow Dash wakes up to a burning Ponyville, nothing is as it seems anymore. She is left with only pegasi that are equally confused, and must attempt to discover what brought Equestria to ashes.
But as time goes on, back, and around, similar tragedies start happening to her friends, affecting the elements of harmony they bear. Can they work out what is causing these tragedies with their different pasts and futures before there’s no turning back?
(Formerly begun as Nightmare and Pinkie's Phantasm, Runining Harmony revamps Nightmare into Dash's Dilusion and combines the two stories before continuing on with other events.)
