The Gates of Tartarus have been breached, releasing evils long since vanquished back into Equestria.
Celestia sends her student Twilight Sparkle to investigate the Gates of Tartarus, but when things don't go quite as planned the young unicorn is forced into a difficult position. Through blood and tears she will be tested harshly, both physically and mentally. With unparalleled strength of self and unwavering faith in her princesses, Twilight takes up a mantle that no pony should ever be forced to bear.
Can't forget to mention Ping111 and Inquisitive Dash for helping out with pre-reading and pointing out errors when ever they have the time.
