Backgammon

Backgammon Fall is an Equestrian Unicorn relative of Cozy Glow and a former student of Celestia's School for Gifted Unicorns. She is a highly talented magic user with a chess-based cutie mark like Cozy which exemplifies her ability to trump the best challenges. But she gets expelled for trying to spread friendship forcefully amongst the stubborn world and disobeying Celestia to do it. This makes her incredibly jealous when her protégé and Princess of Friendship Twilight Sparkle gets the job, and accuses her of stealing her dream. (TBC...)
