As everyone else watches silently, Shae opens the chest in the southwest corner (U). Surprisingly, it is a latch that is shut and locked, but there is no actual lock on it, so it is easy to open from the inside.
The lid opens with a slight mechanical sound behind it. Apparently, it is attached to something mechanical (not magical) in the wall.
The eyeball on the eastern wall suddenly blinks! When it does so, a paralyzing ray shoots out into the room:
Shae...is not paralyzed
Kahan...is paralyzed
Fingas...is paralyzed
Tahldar...is not paralyzed
Leo...is paralyzed
Sark...is paralyzed
Everyone except Shae and Tahldar are paralyzed, stuck in place unable to move as if turned to stone. Shae doesn't seem to notice. She is more shocked by what she sees in the large chest.
It is a body...or rather, a decomposed skeleton of what appears to be a halfling. The wretched thing must have been locked in the chest (by Tarimar, presumably), and then either suffocated or died of thirst. It clutches something between bony hands.
Shae gently pulls out what is clenched. It is a scroll. It has three spells on it: flesh to stone, stone to flesh, and petrify.
There is a tattered piece of cloth apparently ripped from the halflings now rotted clothes. The halfling holds it in its hand behind the scroll. Something appears to be written on it in blood, but the 10 years since Tarimar abandoned this cave have left the words faded.
The words are "DAR HA." You don't know if this is the complete phrase or the control word or anything.
There is a gem in the pelvic bone of the halfling. You surmise that the halfling must have hit it up his...well...rectum, so that it would not be discovered by Tarimar. It is a clear gem like a diamond but with flecks of gold and silver, almost perfectly round, and small enough to fit easily into...

...the palm of your hand. (What did you think I was going to say?)
It is slightly larger than the size of a marble.
After this, Shae turns back to everyone. The paralysis spell is wearing off (lasting only about 2 minutes), and you can all move again.
