Twilight Sparkle is and always will be a delightful and intelligent fraulein. However, when a cult of unicorns who fervently support the Return of King sombra took interest to her, things quickly got out-of hoof.
Day by day, Twilight gained strength, studied the Darkest magics known, and even fell in love with the unicorn mentoring her in these ancient and terrifying arts. She became isolated from her friends, and began to prepare to betray the country she once loved, in the name of glory and the pursuit of power.
This is no fairy tale. There will be war, there will be battle, there will be death, and there will be blood. There will also be romance, ballroom dancing, kisses under the moonlight, and most delightful of conversations too.
