Beyond is a corridor which runs east for about thirty feet, parallel with the room. Withered corpses are nailed to the walls, and in a small alcove at the end of the corridor are carved more of the demonic faces that you have seen. There is another wooden door at the end of the corridor.

Making his way down the corridor, Perry would glance at the corpses along the wall. Checking to see if it was obvious how they died or for how long they've been dead. Upon reaching the door, Perry would open it without hesitation

As his party ventured down that newly discovered hallway, Humphry would elect to go last. And when no one else was looking, he goes to the sarcophagus and lays his hands upon its lid, closing his eyes trying to sense any sort of magical aura that could be emanating from inside. 

Arcana 20

Kic will keep his head on a swivel to guard his companions from anything that may attack. 

Perception:  15

Humphry senses nothing magical about the sarcophagus.p

Perry determines that the corpses have been dead for decades, and have been mummified through some grotesque process to prserve the flesh.

Kic keeps a watchful eye out for threats, but sees none.

Perry opens the door! 

It is locked.

Perry does not open the door!

:D

Seeing the door is locked, Perry pulls out a few tools and once again attempts to pick the lock. "A door is locked to keep us out or something in, the question to this is revealed within. In a few moments the secrets will be known and what we seek will surely be shown."

Lock pick: 18

Coming back from his venture, Humphry stands 10 feet down the hallway and readies Chill Touch, getting ready for something to pop out at them.

The lock clicks, and you enter into the largest room you have encountered so far. There are two doors on the left, one of which is the one you now stand in, and one door on the south wall. The room is completely empty.

Kic will fly up and around examining the room.  Trying not to disturb the dust by flying high.

Perception:  24

Kic sees nothing but dust and mold.

"I'm so disoriented, I can't tell which direction we are going anymore." Perry not having an interest in one door over the other

Kic will go over to the south door and try to open it quietly.

Stealth :  15

Kic opens the door stealthily, and it hardly makes a sound as it swings inwards. This room is without the phosphorescent moss, and even with your darkvision you have a hard time making anything out clearly.

Kic will tap his staff and a magical flame appears on the end.  He will point the end of his staff into the room slowly ready to shut the door and fly back.

Perception: 18

In the dim light that the flames generate you make out a strange form oozing towards you. It is a grey ooze, and it has not fed in weeks. Roll initiative!

Initiative:  13

 (of course i roll terrible now)
