Lark

Lark is a Cupid. She hates to see other ponies upset and will sing with her angelic voice till they are calm. She is the most selfless and caring pony and would sacrifice anything to make someone happy. She loves the rush she gets when she makes two ponies fall in love and she just cries with a huge smile as she watches them grow up and start a family and stick together forever. Lark acts as a mail pony for her small town she lives in (same universe as Kai). Her job is just a cover up as she cannot reveal she is a Cupid.
