Mish890

I was playing Get Eaten (remember that old game?) and this guy with the name with Mish890 comes in and keeps repeating stuff "Death is in your hands" and "Your fate is soon Roblox". All of us in the server just thought it was some edgy 12 year old kid trying to convince us he was a hacker. A few minutes later he left and rejoined the game ,but, this time he joined in with somone I had encountered with about a year ago. 12. 12 walked up to me and left the second he was face-to-face with me. The sky turned pitch black and all the cars you drive into the model's mouth's vanished. I just thought this was some major bullshit and just decided to join a different server. But the only server was the hacked server. I came back later and there were more than 50 people in one server. I had thought the developer was there or something but it was the hacked server. Seconds after I joined I was jumpscared with strobe lights and resized blood decals. The last words Mish890 said before he left the game where "The group shall arise". After he left the map oddly returned back to normal. The only unusual thing was that all these people were still in this game.

The Group
I don't have a clue what the group is or what mish was talking about it. I tried looking for the other people in that whole incident but nothing came up. All the info I have about this group is that it has something to do with Mish890 and 12 and could be some sort of threat.

12
I won't explain it here so if need info on 12, here is a link: http://robloxcreepypasta.wikia.com/wiki/12
