But when one pony feels so lost, so inconsolable, so forlorn, that she makes a life-changing decision that almost leaves her shattered forever, it is up to her friends to bring her back.

When you lose something that you can't replace, when you love someone but it goes to waste, and when the tears come streaming down your face, is there anyone who you can turn to...

...to fix you?

[You + Rainbow Dash/Fluttershy]

You're a fast-flying, teenage pegasus colt with dreams of glory! Having just transferred to a new boarding school in Cloudsdale, you're looking forward to meeting new friends, joining the wingball team, and finally hanging out with fellow pegasi. This year's going to be so awesome!

Except you're the only pegasus around without a cutie mark. And everyone already seems to think you're a total loser, before they've even met you. And your only friend can hardly stand up for herself, much less you. And you're convinced a certain rainbow-maned mare is out to ruin your life. Yep, awesome.

This is the story of your high school days at Wingbury Academy.

After a horrible dream with warning from a foe long defeated, Discord, Twilight Sparkle and her five pony friends face one of their greatest struggles yet. When a mysterious yet powerful dragon proves his strength against her friends, Twilight seeks Zecora's wisdom for answers about both matters. However, things take a dark turn when Twilight finds an old book about an ancient power thought to be lost, The Elements of Magic. With such power Twilight could beat the beast, but at the sacrifice of her friendship with the other ponies. Taking on the burden herself, the pony slowly begins to be corrupted with her own powers. When the Elements of Magic take on the form of shadow ponies and a plot of chaos thousand of years old is set into motion, hope and salvation's only chance may lie in a forsaken power, magic of friendship.
