Hey, late as ever lol.
Oh boy this pic has been in my mind from the day I wrote the script for Diamond's backstory!
Who is Diamond? Who is this sheet of white canvas? Well seems like you need to read my comic: https://www.patreon.com/posts/wmw-prologue-27212894
Rest of the chapters you can find on here: https://www.patreon.com/jadekettu/posts?tag=Where%27s%20my%20Wonderland
Or maybe you just didn't regonize them when they are human lol. Honestly I had to do a human versions because BOY if its hard to make a pony dance.
Anyways, spoiler? Nah I don't think so. Go read the comic if you do think so :V
