the "open" tag refers to the door separating room 8 and 10

the door seems to be a wall, but if the players push it the door will activate, seperate in 4 sections, the middle sections will retract back and slide behind the real wall (you can modify it however you want to, the point is to keep the vault hidden)

"closed" version here: https://inkarnate.com/m/OL2VJm-auction-house-45x38-closed-grid-numbered/

horses as mostly there for scale

if you're gonna use a vtt, I suggest to cover room 9 and 10 w fog of war
