This is the story of Umbra. A unicorn who's past is unknown to her. Born with extreme magical talent, as her parents had. And yet, she's just a filly. She never knew her real father. She was told, That Princess Twilight Sparkle was her mother, and Prince Blueblood her father. Her cousin, Skyla often comes over for visits. Cadence resents her, Shining Armor gives a sad smile when she is around. But none the less, as her uncle loves her. She was told that Twilight died in child birth, this part is true. But I assure you, reader, there is a dark secret to this little mare's name and heritage.
((Note that this is a WORK IN PROGRESS. I have an idea formed, but I need to smooth out the edges... But I will try to update when I can :D))
