The Deepest dark update

The update would be about a new dimension where the ancient guardian (a giant sculk titan) would protect a treasure and also be the final boss.
To acces the dimension first you would need to fight the ender dragon then a new message will appear "The Guardian has awaken" after that using the new villager trades you could get a map to the ancient cities once you get there use the fragments to make a key or a special lighter to start the portal and get to the deepest dark dimension then fight the Ancient Guardian, get a lot of treasures, complete the game and get the achievment "Purified" . (i forgot to say that after the guardian awakens the sculk will start spreading in all three dimensions so when you defeat the Ancient Guardian the sculk will disappear)
