If you want this story, P.M. me; I'm done with this.

Meet, Fragment. A changeling with amnesia. With his memory loss adventure ending before it could begin he is brought before Princess Celestia who takes this lost changeling under her own wing in a hope to mend the two species' relations, but many trials will be had which will strain this changeling's trust between the hive he knows nothing about or the ponies that sheltered him. Fragment's past will pursue him as flashbacks slowly show him what his life used to be...
