First I want to apologize if this isn't the right place to post this, I'm still not entirely sure. Also since it was roughly a decade ago I may misremember some details.
This feels like a fever dream but I remember during the lead-up to Fates we were getting updates about the game through Famitsu I would fairly regularly look for the leaks whenever they would come out, since I was in middle school at the time I was also not great at finding them, because of this I would stumble upon a couple of fake ones and there's a very specific one that has stuck with me since then because I thought it looked interesting. Shortly after the reveal of child units, I believe I saw Rhajat, Caeldori, and Asugi leaked, I saw a different leak emulating a Famitsu page that showed designs for Nohr children based off I believe Lon'qu, Sumia, and Henry. Obviously the "leak" was fake but I still just want to see it again to reminicse and because I thought the mock up was pretty good anybody knows what I'm talking about or can find it I'd appreciate it.
