PrincessMoonHoof

I agree with Lady Leopardess, I have read the book The Journal of the Two Sisters and there were some supporting details in there. I didn't know much about Princess Platinum until I read The Journal of the Two Sisters. If you dig a bit deeper, ( And search within other Canon books!) you may find your answer. I mean yeah Mailittlepony the Rainbow Power dolls were released Before season 4, however, we are in season 7 episode 25 now and we still haven't seen Princess Sterling and/or Princess Gold Lily. Most of the toys that Hasbro has produced are either a new main or cameos. We see them at least once. But like I said, there is no Princess Sterling or Princess Gold Lily through season 1 thru episode 25 of season 7. I hope this might help. PrincessMoonHoof
