RG91cmU= (Doure)

The First Doure Sighting.
I was playing in 1.13.1, I set it up as survival that time. I chopped wood just like every Minecrafter would do, I started crafting a pickaxe, the recipe does not show up as a Wooden Pickaxe, but a Wooden Shovel. I freaked out when I saw this, I started using the Shovel recipe, it was a pickaxe.

13 Minutes later, I mined, searching for diamonds, while exploring a cave, I saw the stone was replaced with Diorite, I then freaked out afterwards, I was then teleported to a single-block island, I saw RG91cmU=. He said the following:

 Hello, George.

 How do you know my name? I freaked out.

 I am Doure.

My Minecraft crashed with the following:

WU9VJ0xMIERJRSBORVhU.

I then converted the message, it showed this:

"YOU'LL DIE NEXT".

I then freaked out, I shut down my computer, never to use the computer again.
