This idea is inspired by Dante's Inferno and it's how I imagine it would be like.
The Stronghold of The Twisted Titan

Giant courtyard to main entrance with
gauntlet of imps and Felguards.

The Forbidden Vault
Two pitlords pushing their door, attempting to close the next entrance,
if the door closes, it's a wipe. So players have to dps the pitlords down

clear path to the door.
