Lyra Heartstrings was born in a normal Canterlot family as an only child. Her father worked for the city's weather team, and soon become the manager when Lyra reached the age of eleven. Her mother was a unicorn, house wife, and took care of the young filly until she was able to head to Celestia's School of Gifted Unicorns. The lyre cutie mark on her flank appeared on the day she discovered her unusual talent to play the instrument with magic produced hands. She graduated at the top of her class from the school, but only to be out matched by the one and only Twilight Sparkle. Who was actually a good friend of hers, and a slight "dirty history" with each other. The purple unicorn, however, left to Ponyville after they graduated as ordered by Princess Celestia. Leaving Lyra back in Canterlot with her other friend Bon Bon.
After which she lived a rather boring life helping the candy-making mare with her business and astounded audiences with her abilities to play the lyre, until one day she was reading through some books in Canterlot Library, she discovered lost beings known as humans. Realizing these human's hand structure was just like her ability to produce hands, she instantly became obsessed with them, and did everything she could to find a way to meet them in person.
Five years later of constant research and going insane with her obsession, she finally learned that the only race that new how get there was the zebras. She knew there was a well-known zebra living in the Everfree Forest, and instantly went to her. The zebra agreed to send her, but once she arrived, Lyra ran into a bunch of thugs. Being drugged up and freaked out by the unicorn, they unfortunately killed her, sending her to her fate in the pits of Tartartus.
But instead of becoming a lost soul in The River of Styx, Soulless Reaper gave her a job to judge the human souls that came down there.
Author note: This all I have on her for now. I'm not sure where else to go with this.
