(EDIT: Shrunken Kuno version here: [link]
I've been reading this fan fiction written by Anonymous Pegasus on FIMFiction.net called "An Affliction of the Heart", and I have fallen in love with it.
After the ending of Season 2, Warden, a royal guard finds a wounded Changeling named Kuno in a field and he takes mercy in sparing her life. You really should read it yourself![link]
