OOC:
OK, a few things:
1) There are effectively 10 doors, as 2 of the doors are outright broken.
2) The other 10 doors (whether the open to a room or open to a blank wall) can only be opened while the groove that Grin activated is lit.
3) The morlocks seemed to only be focusing on two doors at the current time. One is the one that Stee came from and that you entered the room through. You don't know why the morlocks were focused on the other door, but they were.
4) Stee came through the doors you all entered through. Before he could leave, they were closed and he saw a light in the seam between the doors when they did close. When he opened them again they lead to where you were.
5) When you closed the doors after entering, Brewner notices a light in the seam between the doors.
6) When Grin activated the panel by making the groove light up, the doors again showed a light in the seam between the doors. You don't know if that happened for all doors or not, but it did for the ones anyone could see.
7) You opened all of the doors, looked to see what could be seen, then closed the doors. Five doors opened up into various caverns. Five doors opened to blank walls. When the last of the doors was closed, there was a light seen between the seam of the doors again. Also, about that same time, then groove went dark.
The groove is the line under the triangle made of six circles. When you came in, you saw that three of the circles were lit. After Grin activated the panel by running his finger along the groove, the doors showed the light at the seams and a fourth circle was lit up. Now there are only two unlit circles. When the last of the doors was closed, the groove's light went out.
Here's the picture of the panel again:
The background color represents the stone wall. The blue and black circles are the circles of the triangle. Each is a hemisphere that is dug into the stone wall. The blue ones are lit; the black ones are not. The black line underneath the triangle is the groove. It is a half-cylinder that is dug into the stone wall. It was lit when Grin activated it, but after opening and closing all of the doors, the light went out.
Does that help summarize where things are? I feel like I am not doing a great job explaining it. Also, if you want, I can speed past the puzzle part and let you figure out how you want to handle the room. I didn't mean for this to drag out or be too confusing. :-)
