Meet Peter. He is Steve's brother, Well imagine it as a sort of step brother. They are not blood related... But the came from the same place?

Nothing. Yes nothingness, I created that word. They came from nowhere and are the only ones for light years. Infact a Minecraft random generated world is larger then Saturn across. Not exactly a light year, but a fair while.

Peter is (typically) Steve's evil twin.

What else is there to state.?

In other words - Enjoy :D
