At the moment, the adventurers stood in a loose half circle surrounding Zandria as she faced the wall opposite the entrance-except for the swordsman Brunn and the Tyrian priest, who deliberately watched the hallway outside for the approach of any enemy from that quarter. Jack nodded in appreciation; these were professionals, as he'd suspected. He stopped about ten feet short of the two sentries and studied the scene.

Now choked in rubble and ruin, the chamber had once been grand indeed. Two twenty-foot pillars had been carved into the likeness of grim dwarven sentries, guarding the entrance to the room. The chamber itself was a high rotunda, its walls lined with tall columns. A great carving in relief circled the entire chamber, a pastoral scene of grain fields and vineyards. In the center, directly opposite the entrance, stood a smooth glossy stone with a smaller, more intricate carving.

"Zandria's inscription," Jack whispered to himself. "Excellent!"

The red-haired mage stood with her back to him, facing the wall. She carried a long staff of dark, rune-engraved wood and wore a short sword of strange black metal at her side. Holding the staff in the crook of her elbow, she studied a parchment scroll.

"Now, ten paces south from here," she said. "South is toward the entrance, correct?"

"Aye," said the priest of Tyr, speaking over his shoulder. "The hall outside runs straight north and south."

Zandria turned and began pacing straight toward Jack, her expression fixed in concentration. She counted ten paces and then halted, very near the entrance to the chamber. She referred to her notes again.

"Now, I speak the words kharaz-urzu."

As soon as the dwarven words left her lips, a bright silver light softly grew in the chamber. High above, shining orbs hidden among stone carved to resemble the boughs of trees began to glow magically, overpowering the adventurers' own spells of light. The swordsmen shifted nervously, vigilant for any sign of impending attack, but instead of heralding the arrival of some ancient guardian, the light simply cast a glimmering field of slanting silver beams throughout the room as each ray bounced and rebounded from hidden, polished surfaces.

"What's happening?" called out the priestess of Tempus. She whirled from side to side, her battle-axe poised to strike. "Zandria?"

"Hold a moment. Nothing threatens us," the wizardess replied.

She turned slowly, studying the patterns formed by the argent beams. Six rays gleamed in the chamber from six silver apples hidden in the stony leaves at the apex of the room; each reflected four times from smooth, glossy spaces cunningly hidden in the carving that surrounded the room, creating a cage of light that spiraled down to meet at one common point in the center of the chamber-a large seven-sided stone that stood perhaps an inch higher than the rest of the floor.

"The seven stone," Zandria breathed. "Brunn! Kale! Crowbars, quickly! Raise the stone in the center!"

The swordsman, Brunn, abandoned his post at the entrance to the rotunda and shrugged off his pack. The slender half-elf in gray joined him. Both men rummaged through their backpacks and came up with short iron crowbars. Then, silhouetted by the silver light, they worked the tools under one edge of the stone and slowly levered it up. The stone was about six or seven inches thick, and almost four feet in diameter.

"There's a staircase hidden under here!" called the half-elf.

"The Guilder's Tomb," Zandria whispered. She glanced around. "Thieron and Durevin, stay up here and guard our exit. Kale, you take the lead. Be wary of traps; Sarbreen's full of them. Brunn, you follow Kale, and I will follow you. Maressa, you bring up the rear. Any questions?"

"It's dangerous to split up," said the priest of Tyr. "What if you have need of Durevin and me when you get to the other end of the passageway below?"

"We'll call for you to join us if it looks like we might lose contact, Thieron," Zandria said. "All right, then, let's get to it."

The scout-Kale-nodded once and dropped quickly into the stairwell, alert and cautious. Brunn, the big swordsman, came after the thief, jingling in a mail shirt that hung to his knees. Zandria followed and then the priestess of Tempus. Jack debated returning to where his friends hid and then decided that the opportunity was simply too good. He glided forward between the Tyr priest and the other swordsman, who stood watching warily in all directions, and followed Maressa down into the staircase.

The stairwell opened out into a long, low hall, leading into darkness. They advanced a long way, passing entirely beneath the rotunda by Jack's reckoning, and then began to climb back up another flight of stairs.

"We're right behind that damned memorial stone," observed Kale from the front of the party. "All this time wasted solving the riddle, when we could have tunneled or blasted our way through with magic!''

"I am not certain that would have been the case, Kale," said Zandria. "The master stonewrights of Sarbreen had secret ways of strengthening stone, reinforcing against magical attack. It wouldn't surprise me if they had guarded the vaults behind the rotunda with these techniques."

"Door ahead," the thief said by way of reply. A great valve of shining silver stood at the top of the stairs at the end of the secret passage, only six feet in height but almost as wide. The likeness of a dignified elder dwarf was embossed in the center of the portal.

"Cedrizarun himself, I believe," Zandria said. "Search for a means to open it, Kale, but be careful. There may be a trap."

The lockpick nodded and moved closer to inspect the door. The rest of the group fell silent as they allowed Kale to do his work. "Ah," said the thief. "Avoid the handle, here. It triggers some kind of mechanism-a pit trap beneath this staircase, I believe. Instead, all we need to do is simply slide the door aside. It's on a very well concealed track."

"You mean it doesn't open? You just shove it aside like a decorative screen?" Brunn laughed. "Not very secure, is it?"

"That's not all. Some magical force prevents the door from moving. I suspect that we need a password of some kind, as we did above."

Zandria nodded. "Kharaz-urzu!" she stated. Nothing happened. The others waited, shifting nervously, but no silver light appeared, and the door remained immovable. "Damn, I'd hoped it was the same word. Very well, then. Stand back, I'll work a spell of opening."

The other retreated back down the stairs a few steps as Zandria raised her staff and struck once on the silver barrier, muttering old magical words. The silver surface glimmered and then began to roll aside. As it opened, an arc of darkness appeared at one corner and then twisted up and around, replacing the silver wall-the door was wheel-shaped, rolling aside in its seamless stone groove. Zandria waited for the door to move aside and then thrust her staff into the space revealed, conjuring a brilliant burst of magical light to illuminate the space beyond.

Gold glittered and sparkled in the darkness. Jack blinked in amazement; the vault was full! Dwarven arms and weapons gleamed in the light, tall banners from a dozen battles lined the walls, and everywhere he looked great painted vessels and gilt coffers bulged with gold and jewels. A single share of this loot might be worth thousands upon thousands of gold crowns!

"Oh, my," said Kale. The lockpick took one tentative step toward the waiting riches and licked his lips. "Oh, my."

Zandria barred his way with her staff. "We will examine the treasure carefully and completely before we begin to remove it from the vault. Remember, the first thing we want is the Orb. Anything after that is merely a pleasant bonus, and for Azuth's sake, exercise caution! Who knows what traps the Sarbreen dwarves might have planted within the vault itself?"
