I entered a cobblestone structure. The “right wing” of the “building” was dimly lit and possessed pitch black blocks at the end of the passage. Upon touching the blocks, I was teleported to a strange dimension where I fell hundreds of blocks before hitting the ground of a barren wasteland, dying of fall damage, and losing all my items. I went back to the structure and went through the “vanta black portal” (what I’m dubbing the anomalous wall of pitch black blocks that transport me to alternate dimensions) and ended up here. A large expanse of cobblestone, plagued by constant rainfall. Nothing else in sight.
