An old tree house I had built around the late 1.3 range or so. I recall basing that off a build in r/Terraria, but I can't find it for the life of me and it's been a good few years, so that's one of those where it'll look familiar but it's tough to source.
Love this house! The entrance, especially. Are you able to get to the area down below somehow?
Also, why does your moon look that way? I'm about 30hrs into my first world and have never seen that kind of moon
Minor spoilers but some endgame items are Monoliths, which mimic the visual look of a few events like the Blood Moon, this one is one obtainable after fighting the final boss and mimics a late game event visually.
Yes actually, the right side has a teleporter, which leads down below ^^
