Chapter 4: Level 3 dungeon

I will accompany Orsik as he moves to the other chamber.

Nyx figure out nothing is magical in neither this nor next chamber (or if it is then it is well protected against his magical detection). Nyx could recall from books how black dragons look like and Friezes seems to be close to what he have seen. Criella understand that this room is garden and is used to grow some plants watered by sprinkler and grow in this underground thanks to compost. It is strange though why would one grow plans in such a darkness and not surprising they would grow good.

Tinkara flying close enough to the ceiling examine the friezes notices tiny holes in the dragons' mouths.
Orsik find nothing special in next chamber but an exit to another room which is interesting indeed

A four-foot-high, seven-foot-wide iron lectern in the middle of this rusty, iron-plated room is topped by a slanted control panel. Set into the control panel are a gold lever with a star-shaped handle, two dials in red and blue, and two buttons of the same colors. Wall engravings behind the control panel show five groups of circles, with a small crystal embedded in the wall under each one. The crystal under the configuration labeled "3" glows bright green. Three six-inch-diameter rusty iron pipes jut from the wall above the engravings.

Tante Lude and the celestial go forward into the next room. (The control room)

"So, we aren't going to say that name it said to say on the wall and presumably summon an angry black dragon? I'm good with that. Anyone have a good explanation for dealing with this one other than taking the damage?"

I move to the control room with Orsik.

Party quickly moves out of the suspicious chamber with black dragons and possible acid spray and into the control room (not without help of the flying Criella to avoid stepping into another slime)
You feel no magic in either of these rooms (apart from anything magical you have in your possession)

I give the room a bewildered look.

"Maybe the controls change between groups of three rooms? I don't have a clue otherwise."

Tante Lude spoke up quickly when she sees Orsik reach for the level"

"Aren't we even going to look for color clues around here?"

Orsik pulls the Gold Lever to the down position. The slime of similar colour and consistency as you have experienced already begins to pour into the room through the iron pipes above the wall engraving.
It is quite obvious all of this room floor will be covered with the slime in no time.
