(Sorry I haven't posted, I haven't had time to update the map but I will give you the two door glyphs)

Before going back to the last room, Oreus looks at the glyph on the southern door in this room it is a "J". Going back to the pervious room he checks out the northern door, the glyph read an "U". (To my knowledge nobody has been to this door before Oreus checks it out.)

You can go back to the empty room (except for spider webs) and go down the stairs (see post #489 for details), or try the N or E doors at the northernmost part of the long hallway (passed the trapped floor), or check out the branching tunnel (see post #520 for details), or something else altogether.

Ok let’s go back to the lever on the wall and use it and see if it disables the floor trap we have to cross to get to the other doors marked N and E and go use the keys 

"Lets move. We need to find those kids!"

Tyris nods.

Laladak follows the group to the old lever. If no one else acts then he will pull it. 

Shadow lead the group to the the room with the level, pulling the level up in hopes of disabling the nasty pit trap. He leads the party to the map room and illusionary wall to the long hallway. Going over to the trap he hastily steps into the lid of the trap, ready to jump off, but nothing happens.  Relieved Shadow up to hallway. Along the way Oreus looks at the one door he didn't study before and sees the glyph is a "J". Bringing the group to the northernmost part of the hallway, Shadow tries the N door first...

Nothing remains in this room except four decrepit cots, four small wooden chests, and a wooden dresser with four drawers. Everything is draped in cobwebs

(When I was given you opinions yesterday I forgot one there's the gear door in the first room that is propped open with a rock see post #337.

Shadow will Investigate the room for any hidden exits

15

Laladak would like to Help shadow investigate. 

Shadow and Laladak searches the room for hidden doors, but doesn't find anything. 

About the time he is finished searching the second hour comes to a close and the light spells on Laladak's and Oreus' weapons goes out. 

9 for the help

if they don’t find anything we will go open the E door.

Shadow and Laladak still don't find any hidden exits

I'll assume Alben casts 2 more light spells on the weapons. 

After exploring the room Shadow tries the E door. It a is a Mirror image of the pervious room. 

Nothing remains in this room except four decrepit cots, four small wooden chests, and a wooden dresser with four drawers. Everything is draped in cobwebs.

22 to search room, if nothing found I will go back to hallway and search the wall between the 2 doors for an exit north from the hallway since we found one to the south

24

Shadow and Laladak search the new room, but give a half-assed job because the room was so similar to the last one, and don't find anything. Shadow then searches the northernmost part of the hallway with Laladak's help something catches your eye, but you aren't sure. (Roll again adding 6 instead of 4 to your advantage roll)

guys if I though I saw something about this wall you all should look too

Shadow finds a cleverly hidden panel in the wall that when pressed it opens a 4 foot section of stone that perfectly matches the rest of the wall. 

Revealing a room beyond...

An acrid stench fills this chamber, which contains two large tables draped in cobwebs. Alchemical apparatus clutters one tabletop, while the other table has been flipped on its side, spilling its contents into the middle of the room. Amid the fragments of shattered glass lie some candles, some spent tindertwigs, various sundry utensils, and a pile of rags. A five-foot-wide tunnel in the west wall leads into darkness. Against the opposite wall stands a cabinet, its doors set with jagged shards of frosted glass. It looks like someone smashed though the glass to reach the contents within. Mounted to the ceiling is a web-shrouded wooden fan connected to some gears and a rope belt that crosses the ceiling and disappears into the north wall.

(I've updated everyone's Character Sheets to the correct XP values. Shadow was the only person who had the correct amount, though Oreus was only off by 1. Here are the totals 

Alben = 355

Shadow = 310

Tyris = 270

Laladak = 270

Oreus = 250

To make tracking XP easier I have changed all posts with XP to Red. In the future all XP values will be in red. Please try to keep your Character Sheet updated)

Laladak walks into the room, great sword drawn, Ready to swing on any hostile targets.
