Guys i was online today just finishing up my house then i heard that a MILLION DOLLAR sign was hidden inside the spawn. Then i found this small staircase dug on the side of the cliff with SPAWN GATHERING CENTER and Wither Skeleton&Sons Attorney. After going down about three floors, i found
a nether brick staircase. I went down with other players that TPed to me, and the first thing i saw was the sign that said
 "This is where we sealed Plenary in a bedrock tomb. May he and his wrath remain in the darkness forever. And if they do not... Pray he does not find you"
AND
a bedrock tomb, also with a sign: "Plenary: FINALLY! I have escaped!"
i heard that the tomb existed under the new spawn, but i ACTUALLY found it!
soon i got scared and tried to get out i took some screenshots and i TPed to my house
