The party entered a strange octagonal room beyond the narrow passage. The floor was paved with fine flagstone; the high ceiling was well illuminated with continual flame torches. Each of the walls was carved with a detailed bas relief of some fantastic creature -- a tentacled monster with one red eye, a dragon, a fish creature with tentacles and three eyes, a two-headed giant, a spherical creature with four eyes on stalks and a large central eye above a gaping mouth, a gorilla-like beast with four limbs and six insect eyes, and a strange seven-eyed spider creature. On the center of the room was a large carven pillar that stood upon a fresco of an eight-pointed star. Seven of the poitns were black, and one red.
The six adventurers stood gaping at the walls for a minute, before Morderas began searching the central pillar. Thalas pulled out the parchment they had found with Lavinia's signet ring. "Perhaps this is some sort of puzzle -- the red point on the star looks like a pointer." He reviewed the odd message:
Chimera looks to sunrise,
Cyclops looks to sunset,
Medusa looks to sunrise,
Umber Hulk looks to sunset,
Basilisk looks to sunrise.
"Does anyone see any of these monsters on the walls? I don't. The sunrise-sunset think probably means east or west, or left or right, but how to match the walls?"
"Hey, the pillar turns!" Morderas announced. He and Thalas combined their efforts and rotated it, tentatively, one turn. The pillar had eight defined stops, one with the red pointer pointing at each of the seven bas-reliefs and the entrance corridor. The rotated it back to its starting position.
"Well, it's some sort of combination lock, and the riddle is the combination, but Corellon be damned if I can match the monsters on the parchment to the ones on the walls," Thalas grumbled.
"It's eyes!" Athal announced suddenly. "Look at the monsters' eyes! One ... two ... three ..." He pointed at each wall in turn. "There's up to seven numbers."
Thalas looked down at the parchment. "Well, a chimera has six eyes, a cyclops one, a basilisk two, I think. Do a medusa's snakes have eyes? Or does a medusa count as two? And how many eyes does an umber hulk have?" He'd certainly heard of all the creatures and seen drawings in books he had studied, but he'd never really paid close attention to monster eyes.
No one else knew, either. "Why don't we try this combination idea," Athal suggested. "We may be able to figure it out."
Thalas and Morderas started by rotating the pillar six points to the east (right), listening intently, then one point west (left).
"I heard something" Arjan announced. Quinn nodded agreement. "Just then when you turned it. A soft 'click'." Thalas continued rotating, two right, two left, two right. "I heard a few more clicks," Arjan said, "but not on all the turns."
They retraced their pattern again, with everyone listening intently. "We've got it right, except for the umber hulk," Athal concluded. "It must not have two eyes."
"Well, I'll try three, then four," Thalas replied. He and Morderas went back through the sequence twice more, when Arjan suddenly exclaimed "I head it!" after the second try.
"Guess an umber hulk has four eyes. Or is wearing glasses," Thalas concluded, finishing the sequence. Nothing had happened. "Now what?" He returned the pillar to its starting position, and there was a sudden grinding noise as five of the walls slid aside, revealing five niches containing a number of large iron-bound chests. "Oh. Guess that's it."
