update 1today i went to the nether and dug up till i saw bedrock. i switched to creative with tmi and all of it was bedrock.
i have heard that if you put lot's glowstone down you can see a gold house. i think it is herobrines. maybe they have only left him there in the game. or is it just his house that was there and the people i have heard from may have the herobrine mod. who knows??????
