Lyra Heartstrings. When she was accepted to Celestia's school for gifted unicorns many had high hopes for her. She was a skilled musician and showed promise in the little understood field of love magic. By all rights she should be either performing to an audience of thousands now or be a personal student or assistant to Princess Cadence. What she is instead doing is working a part-time job in a coffee shop in Ponyville.

Her life didn't go as expected but that is not necessarily a bad thing.
