Welcome to the Sleipnir institute for the mentally unwell, where the most dangerous ponies in existence are contained within small, metal cells designed for the sole purpose of imprisoning them. It is in this grim, dark place that the alicorn princess Twilight Sparkle finds herself, her wings bound and her magic disabled. Twilight doesn't know how she came to Sleipnir or why, and every time she turns her mind to the past, she feels only pain. Twilight can do nothing but piece together enough of the past to find out why she was imprisoned. It will not be easy, but Twilight has the help of others to assist her, a crippled pegasus, a cannibalistic psychopath, and mysterious machine named Dread.
