Section 4 - Behind the staircase
A room called Behind the staircase is north of the lobby. "A floor to ceiling wall of glass stands to let even more light into this two floor lobby. The stairs create a small alcove as they go above your head. The more open portion of [the main lobby] is to the south."
A trapdoor is down from behind the staircase and up from the dungeon. The description is "Wooden planks lay in-line on the floor under the alcove created by [the staircase]. It has a handle for lifting. The words [bold type]Dungeon - Adult Content[roman type] is wood burned across [the trapdoor]." It is a closed, openable and locked door.
Understand "planks" or "wood" or "door" as the trapdoor.
Instead of pulling the trapdoor, try opening the trapdoor.
A bust of Devin Weaver is here. The bust is fixed in place. The description is "Standing on a marble pedestal is a stone bust of Devin Weaver. You know this because someone took the time to carve a name tag onto the chest portion of the bust. There are four buttons inset in the top of the pedestal each a different color. Attached to the pedestal is a sign that describes what the buttons do. (Try EXAMINE SIGN to read it)."
Understand "devin" or "weaver" or "pedestal" as the bust.
A button is a kind of thing.
The green button, red button, white button and black button are buttons and part of the bust.
The description of the green button is "An arcade style button the color of green.".
The description of the red button is "An arcade style button the color of red.".
The description of the white button is "An arcade style button the color of white.".
The description of the black button is "An arcade style button the color of black.".
Instead of pushing a button, say "You push [the noun]. Nothing seems to have happened."
Instead of pushing the green button for the first time:
now the trapdoor is unlocked;
say "You push [the noun]. You hear a [italic type]click[roman type] coming from [the trapdoor]."
