Immersive Ink

We already looted these zombies the first time we killed them, didn't we? If not, I'd like to check for anything useful they might have on them.

Grampus says, "Some incremental improvements should occur since they've eked out or better since we last had the pleasure of their presence. Goes to them being existing, assuming they are, that they build on their assets. Need a zombie wealth advisor to help us. Or we just run them through with swords and discombobulate and see if anything of value falls out.""

Attempted a map correction! Hopefully that's more accurate.

"Friend Grampus, your assessment seems sound!"

Yes, let's check the zombies for anything interesting they may have accumulated since their initial demise, and then proceed back through the elevator room & northward.

All good on map except the north passage is 20 feet from left edge, not 20 feet from right edge

Yup, back through the elevator room and then north, once we've looted the zombies.

Sounds good.

OK, no loot on zombies

The north passageway is 30 feet to the left of where acodispo drew it, and goes 10' to a door, where you do not hear anything. You open the door onto a large room filled with green gaseous vapours

Maloof quickly retreats away from the vapours!

Aldbane also retreats. "Close the door, quickly!" he says.
