The Story
At my school, Minecraft was the most popular game and all of my friends played it. We built cities, played mini-games, and made videos. One day, we played on one of my friend's worlds. He opened up for multiplayer, and the other three of us joined. We started building some houses, until things got weird. One of my friends, Synthex, posted a comment that said "He Is Here.", before disconnecting. I didn't notice until one of my other friends, CHester13, pointed it out. My other friend, Chowguy, thought that he had to go to bed, and we all agreed. Ten minutes later, we discovered a village, but it was burning down. Me and my friends investigated, but there was no fire or lava source nearby. We put out the fire one of the houses, only to find a sign that said "He Is Here." We now thought it was a prank by Synthex before he disconnected. Later, when we were adventuring in a cave, my friend Chowguy spotted a faint light source in the distance. We followed it, and we found a redstone torch with a sign that said "Evaman Is Here." We now thought that Synthex might have not pranked us, because we never explored down this passage before. Also, this was a new world and we never switched to creative mode. Later, my friend CHester13 thought he saw a green player, though us three were the only players on the server. Chowguy and I ignored it. Later, we saw a comment that said  I Am Here. Now my friends and I were really freaking out. CHester13 said his game was glitching and he saw the green figure from before but closer. That was the last comment he said, because it said in the chat, "User:Evaman removed User:CHester13 from the server. I brought up the player list, but the only players that showed up were awesomefighter (me), and Chowguy. Then, a comment appeared that said, "Evaman Is Back." Chowguy and I hid inside of an underground base. 20 minutes later, nothing happened. We came out of the base to get some food, because we were getting low on food. We went to our house to get some food, but our house was burning down, and the chest and its items were already consumed by the flames. When I looked to my left, my friend, Chowguy was randomly taking damage, though nothing seemed to be causing it. I couldn't do anything to help him. In the chat it said, "Chowguy was killed by magic." 3 seconds later, the chat said "User:Evaman removed User:Chowguy from the server." I wanted to quit, but I wanted to find out was this entity was. Later, the chat said, "Now It's You And Me." I was freaking out. I was about to quit, but my keyboard wasn't working and my mouse wasn't moving. 2 seconds later, Minecraft crashed. I read the crash log, and it said "User:Evaman removed User:awesomefighter from the server." 5 seconds later, my computer shut off and I couldn't turn it back on. I never saw this entity again, neither did my friends.

The Truth
The next week, my friend Chowguy said it was a prank and said that Evaman was his account and he invited it to the server in creative mode. Also, he used it to delete my other friends. But that still doesn't explain how he made it so my game would crash and he made it so my computer would shut off. I'm convinced that it was just a bug on my computer, but it might be something far more sinister.
