Tells the story of how princess Celestia came to be; An incredibly mature story almost professionaly written(Action, Death, Slice of life, Sad)

Twilight's Midnight Violations
A curse in the sparkle family turns Twilight upside down making her do something that will change her life forever, this is clop but really nice one with a deep story and consequences(Adult, Herm(futa), Dark, Evil, Slice of life)

An affliction of the heart(all of them)
Know the awesome story of Kuno, a changeling with an attitude as she finds out about love, the equestrian way. This is pretty much the fic that made me love changelings(Comedy, Romance)

Greenfire
An alternate universe where Spike never was hatched by Twilight so he grows up on his own, best Spike-Rarity story ever made(Romance)

Millenium Wake
Rarity Falls into a 1000 year slumber and the world has changed for the worse, follow her into a post apocalyptic mayhem...IMHO this story puts Fallout: Equestia to shame...also for some weird reason developed a fetish for scorpion tails...as long as they come attached to a marshmallow (Sad, Dark, Adventure)
