Conspiracy theory: Inferno Staff

i dont know if ive missed something or found something but i found a gigantic wooden square that is like worldedit gigantic and i found a sign saying here lies inferno staff i went under it and found a passage far below the earth.
I found a empty chest and a crafting bench. further on was a 6x6 square going down to bedrock with lava at the bottom. I tried to build a brige over but i got denied acces i still remember the location and if this is a new discovery i will be glad to tell if you can cough up some materials or GP. If it isnt a new discovery but its very old then please do not post troll/ hate comments just say its old and not legit or say its already been found and its empty

If it's north from spawn and has huge wooden walls then it was discovered long time ago
