After Varachan's monlogue, the three cultists (Varachan, Naquent, and the one-eyed Hag) go pull on the lever in the corner of the room and vanish from sight.
A couple of minutes later, Kerwyn (and all the other contents of his cell, disused bowls, etc.) abruptly disappears from his cell.
Kerwyn reappears in a 60' by 40' stark chamber that has a single closed door for an exit. The room has a large black lever set into the middl eof the floor, standing about four feet high. Around the base of the lever, a 1 foot diamater dial can be adjusted to point to any of twelve numbers. Just behind and to the right and the left of the lever, two 10-foot circles are inscribed into the floor and filled with silver.
Kerwyn finds himself in the left of the 10-foot circles and the dial next to the lever is currently set to the number 8.
Kerwyn finds himself encircled by the ugly hag (who now has two eyes), Varachan, and Naquent. Naquent has her dagger in her hand and the muscles of her hand continue to twitch uncontrollably.
Varachan speaks, "Now, Kerwyn, I know that you are purveyor of fine jewels. The orb of golden death was set with four jewels. If you don't know of it by that name, it was also called YellowSkull, Goldenskull, and Death Orb. Perhaps you could tell me where the jewels are. Don't worry about the Garnet that was the Elemental Gem of Fire. I want to know about the Elemental Gems of Air, Earth, and Water ... one was a Smoky Quartz, one was a Carnelian, and the third was an Aquamarine.
"The destiny of the world depends on your answer.
"I am certain you can give me at least a hint as to where one of the gems might lie."
