Chapter 2: Rotten Halls

Vatoris slaps the mask out of Throgin's hand. "Please do not place strange stuff on you without allowing me to check it first. We... You have no idea the manner of curses and evil magic that could be on it..."
Vatoris starts casting Identify on the Mask. Once that is finished he will do the same to the magical disk...

"And don't poke strange eyes," Ixion added, "but I'm more concerned about what's in this sarcophagus."

Throgin is quick to put a mask on his face before Vatoris finish his sentence. Putting that mask on has no any obvious effect.

I will sit down outside the doorway of the room and, if we're going to be there an hour, take a short rest.

While waiting for Vatoris ritual casting you notice that the eyes on the disk that keep scanning everyone is ignoring Throgin since he put the mask on.

The phenomena is later explained by Vatoris who learned that one of the masks we trying to identify is just a mast, but the eyes on the disk have some unique magical feature - these ayes have darkvision out to a range of 30 feet. If the eyes spot any humanoids inside the tomb, it was able to awaken the undead and order to attack (at least until you destroyed them). The disk of eyes can't perceive any humanoid that dons one of the papier-mâché masks you see in this room.

I will re-cast my Light cantrip on my wand. Are we gonna try to open the Sarcophagus?

"I can't wait, Tink. Let's all get masks first, though."

Ixion took a mask even though he didn't relish wearing something previously worn by undead.

Zean - seeing that it seams everything is ok with Throgin and hearing Vatoris words - put his mask on, and stands next to Sarcophagus with his friends, ready to help with opening it.
"Yeah... I have the feeling that we ALL should wear the masks before opining sarcophagus." - he looks meaningfully at the others that still don't have the mask on.

Tinkara retrieves a mask, retreats to the other side of the broken window (out of the room) and, landing on the floor, holds the mask up with two hands as best she can, since it's probably half as tall as she is.

Ready as I'm going to get.

After resting everyone put on the masks despite strange feeling and unpleasant smell and Zean try to push aside the lid of the sarcophagus. Moment he touch the lid you hear some clicking like locking mechanism triggered.

"What the..."

The lid is heavy and wouldn't move initially, Zean realize it need to be moved upwards before pulling and manages to open sarcophagus with an effort. You can see locking mechanism inside that appears to be unlocked at the moment for whatever reason.

Creature bones lie in a dusty pile within the sarcophagus that initially look like small humanoid, but the sharp teeth as well as sharp claws on both hands and feet give out it is a sort of an animal. A ring rests atop the pile. The ring radiate an aura, but I can't make it's magic school, most probably it's magic item Vatoris announce

Try to recognize creature.
