I found this block in the gallery biome called the "Vismruqualia block" and I accidentally clicked on it to be teleported here in this weird unending maze of plastic and yellow lights, I can't die and go back to my spawn, it just brings me back here, I can't dig my way out it keeps going on forever, not even going up leads anywhere, how do I get out of here and what the hell is this place?

Ok so maybe this is because I've only ever played on one qualia, but everytime I go up (which I struggle with a lot) I find nothing but the same biomes, when I go down tho? I arrive in a hellscape of a very deep ocean seperated by onyx islands and nothing else, and going down again I arrive in the game's version of the End from Minecraft with sand and dirt mountains for kilometers and only stick figures (idk what they're called lol) and agates, there are zero other biomes in both cases trust me I've looked, is this supposed to be the case? I heard as you go down there are other biomes, unique biomes even, are these the biomes in question?

I got attacked by a small black chess piece and it dropped something called "agate", I can't find anything about its use online, does anyone know what to do with it or better yet how to make its capsule?
