The ponies have had it with Discord's pranks, and when they all wish he no longer has his magic, under unexpected circumstances, it comes true. It's a relieving occasion for the ponies--up until Discord falls deathly ill. Ridden with grief at their selfish wish, the ponies venture off on a small journey to save Discord's life, and recover the draconequus's magic from the beast that's keeping it hostage. The clock is ticking, and through their small journey, they learn that the price of chaos was nothing to pay in comparison to losing someone they love.
Based off the events of "Broken Spirit", and you must at least understand the plot to understand this fic.
