After helping Pipsqueak get elected as the Student Pony President, the CMC notice that Diamond Tiara is not being her bossy, rude self. Rather, she's much more quiet and reserved, to the point where she has all but shut down. Not only that, but her body seems to be changing as well, and not in a positive way. Being the nice fillies they are, the CMC go to investigate Diamond's situation. However, they may not like what they end up finding out.

(This is an alternate story altogether for Crusaders of the Lost Mark. This will contain dark elements so if you do not wish to be subjected to any of them, I suggest you turn away now.)
