The Image

 There's an image related to the show that has had my mind in a grip for 2 years, undeniably from before the show itself was made.

This image, as far as I know, originates from this post , I do not know where Kasa got the image nor have I ever found out if this image was simply promotional material or if it came from a pitch bible or even a pilot animation. I know that the image IS official, those are the same designs from a tile presumably from a background artist on the show that went up for auction.

I desperately want to know just where this image is from, where Kasa even got it, and if I could ever be able to see anything more from this show's production. If you know anything about it, please get in contact.
