I think I’m in an arg.
me and my friend started a bedrock Minecraft 2 player realm. Fully vanilla no mods added at all, everything seemed normal, we used a mojang seed template (jagged peaks) and stayed in the spawn area for most of the time until about day 10, on day 12 my friend saw what he said to be about 2 or 3 floating trees about 20 blocks apart each. This was maybe 700 at max blocks away from spawn, most likely not a sign of corruption, he later saw a random crafting table in the middle of nowhere, we never went where he found it. then it started showing more signs, I went offline for football, he stayed on, he had gone to the nether in search of ancient debris and while mining a pigmen randomly dropped from the sky and just stared as long as he had it loaded in his chunks, later, he was still mining and in the corner of his eye he saw a fully blacked out figure with quartz in his hand which later disappeared, he was then at our base which I was working on, he saw in his peripheral vision the same blacked out figure now with a white cross on his chest moving its arm and then disappeared. I personally have no record of these things but he is going to keep a clipping software up and a recording of every time he plays, I will put the footage in the comments if seen.
