Cael laughed at her, clutching his bruised ribs, as she rubbed her stubbly pate. “A staff is no weapon for a thief,” she repeated ruefully.
“It saved both our lives at the pit trap,” Cael said, remembering with a shudder how, a few moments after entering the vaults from the sewer, the floor had dropped out from under them. Luckily, the pit had been narrow. Cael’s staff wedged itself against the walls, stopping his fall with joint-popping suddenness. Pitch had caught his legs as she tumbled past, else she’d have dropped to the spiked floor forty feet below. They had then climbed out, and after several minutes of tugging, managed to free his staff.
The dark-eyed thief nodded grimly, but continued to look at him savagely as she rubbed her head.
The floor ground to a halt, revealing a subterranean passage. Globes of magical light hung motionless in the air at regular intervals down the passage, which curved to the right. This place was different than the passages they had encountered thus far. It looked carved from solid stone, but by what tools neither of them could guess. The walls were polished as smooth as glass, the floor was like a mirror that reflected and multiplied the light of the magical globes.
“What now?” Cael asked, as he rose and dusted himself off. He picked up his staff and thumped it against the shining floor, testing its solidity. It rang like metal, echoing loudly.
“I wouldn’t do that again,” Pitch said. “No telling what it might alert.”
Cael nodded. Pitch checked the edge of her sword, then stepped forward, tentatively, ready to snatch her foot back if anything untoward happened, like the floor turning to molten lava, or springing sword blades. She knew to expect anything, but nothing happened. She took another step, then looked back at the elf.
“Come on,” she whispered. “It’s safe.”
The passage took them in a large circle back to their starting point. As they approached the small section of ordinary floor where they had started, they paused and glanced up the shaft they had descended, then continued ahead for a second try. On this circuit, they were more careful to look for secret doors, hidden latches, sliding walls, anything that might indicate a way out of this circular maze. During the third trip around, Cael made it a point to touch each magical globe with the tip of his staff, hoping that one of them might be the key. But once more they came around to their starting point.
Pitch stopped and slammed her sword into its sheath. “This is pointless,” she said dourly, as she gazed once more up the descending shaft “And now we can’t even get out.”
Cael scratched and rubbed his chin thoughtfully. “The thing to remember,” he commented, “is that this place was made by dwarves. To succeed, we must think like dwarves.”
“Do you mean, think low? Perhaps the exit is at dwarven height?”
“Or maybe it is simpler than that. Maybe we are just going the wrong way,” the elf said as he turned and looked back the way they had come.
“What wrong way? It is a circle,” Pitch argued.
“Maybe it isn’t. Maybe it is a spiral,” Cael said. At his companion’s skeptical look, he explained. “On the surface world we tend to think in two dimensions, this way and that. But aquatic races like the sea elves, and tunneling races like the dwarves, always think in three dimensions. Try to think of this place as a metal spring. Viewed from above it is a circle, and if you run your finger around the top, it is a circle. But turn in the other direction and go the other way, and your finger should find the spiral of the spring.”
“That’s nonsensical,” Pitch said scornfully. “If we went round the other way, of course we would end up right back here, just like all the other times.”
“It wouldn’t hurt to try,” Cael countered.
With a deep sigh for the foolishness of all elves, Pitch motioned for him to lead the way.
And when they had been walking for about ten minutes, her look of scorn had changed to one of obvious admiration. Cael tried not to notice it, but as he led the way, a bit of a swagger appeared in his step.
Finally, the passage began to level out, and the last magical globe came into sight. Beyond it opened a vast dark chamber. Pitch gazed longingly at the magical globe hovering teasingly just beyond her reach. Cael’s earlier efforts to knock one down with his staff had proved fruitless.
Side by side, they entered the mysterious chamber. Pitch prudently drew her longsword, while Cael peered about, trying to penetrate the shadows with his elven sight. The lights from the passage winked out behind them. High overhead, at the apex of the dome-roofed chamber, another magical globe began to glow, shedding a dim illumination over the large circular chamber. They began to see…
Pitch gripped the elf’s shoulder, her indrawn breath a hiss. He spun, ready for whatever danger she had seen, only to find her grinning like an idiot. “This is it!” she whispered excitedly. “This is the Chamber of Doors! We made it, just you and me! One more challenge, and we triumph!”
“What is the final test?” Cael asked.
“We must choose a door,” she said, sweeping the circumference of the room with a gesture. Spaced regularly around the room stood seven doors, each set at one of the cardinal points. The eighth point was occupied by the passage through which they had entered. Four doors were made of stone, two of iron wrought without seam or weld. The seventh door appeared to be made of purest silver. It glistened in the dim light. “Behind one of them lies the treasure chamber of the Kal-Thax.”
“And the others?”
“Death,” she answered grimly, all traces of merriment vanishing from the hard lines of her face.
Slowly now, they walked the circumference of the chamber, each silently contemplating their choice. No single door held more promise than the others, at least not at face value. Each was massive, built on the grandest of dwarven scales. One of the stone doors was circular, like a great plug of rock. It was roughly hewn, made to look like it was part of the surrounding stone, but Cael quickly spotted a tiny keyhole in the very center (Hammerfell had told him many times about the doors of the dwarven city of Thorbardin, and how they were fashioned). Another door seemed but a stone etching of a towering arch. In the lines of the etching glimmered a thin vein of silver, while the door itself was covered in ancient dwarven runes. The other two stone doors faced each other across the chamber. Both were carved fantastically-one with fauns and centaurs, elves and unicorns; the other with hideous creatures leering up out of the Abyss.
The iron doors also faced each other. Neither bore any sign or device its contents. One door had no visible lock at all, while the other was draped in anchor chains and mighty padlocks. Lastly was a silver door. It faced the entrance to the chamber, and was the smallest of all the doors. Upon closer inspection, it proved not to be made of silver at all, but of the scales of some silvery fish, perhaps. Yet they proved hard as granite and as difficult to mar. This door had three locks of obvious complexity. Pitch tried to examine them more closely, but the light was too dim to see anything in detail.
“You have made your decision, then?” he asked her.
“No, I was just studying the problem,” she sighed as she sat back on her heels. “It isn’t easy. Which door do you think a dwarf would choose?”
“The least obvious,” the elf answered.
“Well, they are all rather obvious,” Pitch observed.
“It must be some kind of trick.”
“Except for the plug door. It took me a while to find it,” she said.
“Indeed, a door that does not seem a door is the dwarven way,” Cael said. “I can think of no other solution.”
