I'm looking for the original source of the image of a castle/some castles that's often used as the cover image of Minetest Game, as used on the ContentDB page, in the screenshot gallery on Minetest.net, and on a lot of 3rd party sources for Minetest downloads or discussion. Here is it in case you've been living under a rock and missed it:

I have figured out where it's from and will share it, but I would really like to be able to play in the world, and am not looking to painstakingly hand-recreate it. I would like to take an 8K screenshot with all latest lighting effects from 5.9.0-dev applied. This 'improvement' approach is what I used in prior work like my recreation of the famous Advtrains image, though the build is already good here, there's just not enough pixels to do it justice (or fit into a print.. - not for commercial use, was thinking more of sourcing images for a future roller baner).
So, I am asking for any help in getting a download if someone has it. Pretty please?
The questions and answers are threefold. Thankfully, after some extensive browsing, and a bit of git archaeology, I managed to find a reference to pull request #143 against the Minetest.net website repository, which explains things.
Q: Who is the original author of the builds shown? My best guess was Miniminaut, given a lot of their screenshots have a very similar architectural style. Miniminaut never uploaded anything to the Maps subforum as far as I know though.
A: Yes, according to Treer, Miniminaut is the author.
Q: Where is the world that has the builds now? Is it a server or singleplayer world? Is the server still up or the world available for download? Returning to the theory fact that Miniminaut is the author, it may be on servers where they played on, like IFS (tried it, was pretty interesting, but didn't find the castle) or Hometown (R.I.P., not sure how many backups there are of it).
Partial A: Yes, according to Treer, Miniminaut made the castles on Hometown server, at (-5640,-10080), and the image is a recreation and improvement of this one from 2018-05-19.
The question remains as to whether this area was backed up, and if so, who by and if they are still around and can/will publish it. I'm really only interested in the Miniminaut area in particular, though of course a lot of other places on Hometown are of historical significance. Later I will try to see what I can find, but the thread is quite long and links die, so it may be a long but unfruitful search.
Q: Who took the screenshot? The build's author, or someone else? And who suggested it be used in Minetest and/or Minetest Game marketing materials?
A: As the pull request author, Treer, mentioned, they took it themself. It was then accepted into the website gallery; and since then has probably been copied many times to different websites, and by (I think) rubenwardy or LMD onto the Minetest Game ContentDB page.
Again I'll restate the main question: Does anyone have a backup of that area of Hometown - around (-5640,-10080), - with Miniminaut's castle intact? Would you care to share it?
Edit 2024-03-15: Fixed image link by retargetting at ContentDB. The castle was on Minetest.net but the only MTG screenshot left there is the last one now, captioned "where it all began".
