It all started when I created a new Minecraft world to record videos for YouTube with my friend, it was on survival and the world type was infinite. I made the seed 'Blank', thinking it would be funny to literally have a blank seed., me being a person that likes dry and bad jokes. I made the world and told my friends on Discord. It was a small group, only seven people, one of which doesn't have Minecraft.
I spawned in a plains biome, close to a small puddle of water and a lonely tree. Further in the distance there was a forest and a group pumpkins. I headed to the forest to collect wood for my house and anything else you'd need with wood. Just when I started moving, I realized my X and Z coordinates were relatively close to 0. I shrugged it off and continued. The forest was both birch and oak. I cut down a couple of both types but decided to only use oak when building my house. Once I got enough, I noticed a ravine nearby, the only thing keeping it from being flooded are a few blocks of gravel. I broke the gravel thinking I was funny and all of the water close to the ravine streamed in... I hoped. Minecraft physics don't work like that. I could've sword I saw the shape of a player teleport away when it hit the water, but shrugged that off too. I crossed the ravine and built my house and created a crafting table. I then realized nobody joined yet and looked on Discord. They said they couldn't join, I checked and online was on. I just told them it was probably their internet being weird and continued.
I looked around for a cave once I was done with my house, but nothing was in sight. Using the water, I nervously went down the ravine. I then realized I only needed stone right now. I facepalmed, collected a bunch of stone and went back to my house. I created a furnace, a stone sword and a stone pickaxe.
When I got outside of my house, I saw a player on the other side of the ravine. the skin was like a block without textures: purple and black checkered pattern. I freaked out and tried to leave the world, but the save and exit button was missing. I was too panicked to consider closing my console. The other player teleported one block forward until it got to me, and I was paralyzed. Once it got to me, it went inside of me, causing my vision to only be the no texture block. I became sane again, but couldn't move my character. After a few seconds, the creature went back a block and I could move again. It grabbed a bow and shot my character immediately, killing my character instantly somehow.
I didn't respawn at the normal spawn, but in a room filled with the no texture blocks, nothing else. I noticed one of the walls had a pattern breaker in it, and it seemingly got closer to me. I quickly noticed it was that creature again. I turned around, just a wall. I could not go anywhere it slowly closed walked towards me, and the game crashed when it touched me. I didn't open Minecraft again until the day after.
When I opened Minecraft, my character was the same as the missing texture creature, who I decided to call "Blank". My worlds were deleted, but everything else was the exact same, except for the cave sounds playing at random times.
