With his left hand, Darien raised the dented pewter goblet that a serving maid had plunked down before him. His nose wrinkled in distaste. This swill passed for wine? He thrust the goblet back down, then noticed a ruffle of purple velvet peeking out from beneath the heavy black cloak in which he had wrapped himself. Hastily, he tucked the bit of velvet back beneath the cloak, then adjusted the deep hood that concealed his visage. It would not do to be revealed as a member of one of Waterdeep's noble families. Commoners would be too wary to speak to a lord. And speaking with the inn's coarse clientele was exactly what Darien needed to do this night. A curious excitement coursed through him. There was always a certain lurid thrill to slumming.

A black beetle scuttled before him across the knife-scarred wooden table. Darien withdrew his right arm from beneath his cloak. The arm ended, not in a hand, but in a cap of polished steel that fit over the stump of his wrist. It was cylindrical in shape, without mark or adornment, save for a single slit on the end.

Darien called it the Device.

He considered his choices for a brief moment, then nodded to himself. The stiletto would do. With a click, a wickedly thin blade sprang from the slit in the Device. In one swift motion, Darien lashed out and skewered the beetle. He raised the blade, staring in fascination at the insect wriggling on the point. Its vain struggle made him think of the hapless commoners who sought glory in the depths below-fighting on when they were already dead.

With a sigh, Darien flung the beetle into a corner. Retracting the stiletto, he concealed the Device beneath his cloak once more. He supposed he was being too hard on these poor people. They had little enough to brighten their drab lives. Why begrudge them what small entertainments they could find? Certainly Undermountain was more than vast enough for nobles and commoners alike.

It was only in recent years that venturing into the depths beneath Mount Waterdeep had become a fashionable-if perilous-sport. Yet it was well-known that the maze was far older than Waterdeep itself. Over the centuries, countless tales had been spun about the city beneath the city, though most were half-truths liberally sprinkled with falsehoods: outlandish tales of imprisoned dragons, monsters of metal, and subterranean forests impossibly bathed in bright sunlight. Still, nearly all the stories agreed on one point, and Darien supposed there must be some degree of truth to it-that the labyrinth now known as Undermountain was created by the mad wizard Halaster over a thousand years ago.

No one knew from whence had come the one called Halaster. A few tales whispered in passing the name Netheril, the dread empire of sorcerers that legends told lay buried beneath the shifting sands of the Great Desert Anauroch. When Halaster had first come here, he found Waterdeep no more than a rude fishing village huddled by a natural harbor. Ignoring the villagers, the wizard ascended the slopes of Mount Waterdeep, and on a rocky shoulder he built a tower for himself, that he might continue his arcane studies away from all distraction. Yet-and here the tales agreed once more-the solitude of the tower was not enough.

Whether compelled by magic, madness, or some burning secrecy, in time Halaster began to delve into the mountain beneath his tower. As the years passed, he dug ever downward, excavating vast chambers in which to work his magical experiments. Some say that as he went he struck delvings deeper and more ancient yet-the tunnels of dark elves and dwarves. From these he drove the drow and duergar, and claimed the tunnels for his own. Eventually, Halaster abandoned his tower, and the uppermost levels of his labyrinth as well. Deeper and deeper he went, driven by his secret needs, until he passed from all knowledge. Soon, hordes of dire, nameless creatures crawled out of the cold and lightless Underdark to haunt the empty corridors and chambers that the mad wizard had left behind.

In later centuries, as Waterdeep grew from lowly village to teeming City of Splendors, it pressed against the rocky shoulders of Mount Waterdeep. Eventually, those who haunted the sewers beneath the city found places where the maze of foul waterways came in contact with Halaster's delvings. Knowledge of this fact soon spread among elements of the city's underworld. Thus the upper halls of Under-mountain became a refuge for bands of criminals and cults dedicated to evil and forbidden gods. When the hidden Lords of Waterdeep finally assumed control of the city a century ago, most of these sinister organizations were rooted out and destroyed. After that, Undermountain was left to brood in its own silent darkness.

That is, until Durnan the Wanderer ventured below.

Durnan was the first to descend into Undermountain in recent times and return bearing tales of wonder and the riches to prove them. Seven times Durnan journeyed beneath Mount Waterdeep, and seven times he returned triumphant. At last he retired from the adventuring life and built his inn, the Yawning Portal, right over the entrance into Under-mountain he had discovered. Some whispered that it was upon this very spot that the tower of Halaster once stood.

All that was nearly twenty years ago. Now Durnan was a gruff innkeeper, not a hero. Yet he kept the Well of Entry ever open. Would-be heroes came from all over Faerun to pay one gold coin and take their chances in the maze below. A few of them found wealth and fame. Most of them found death. Either way, lucre changed hands in the tavern above as bets concerning the adventurers' fates were settled.

Nor were common freebooters the only ones drawn by the sport of Undermountain. Of course, not the least member of the nobility would be so gauche as to pay to use Durnan's public entryway. Many nobles had constructed their own private entrances into the labyrinth, and the rest curried their favor. To the nobility of Waterdeep, venturing into Under-mountain to hunt trophies of kobold or goblin was no different than the manner in which country lords rode into their greenwoods in search of hart or stag. Always the nobles went in large, well-armed parties and ventured down only well-known passageways. There was little true danger in these excursions. It was an expensive and stylish game, and that was all.

In contempt, Darien eyed a scruffy band of adventurers sitting at a nearby table, making drunken plans for their own descent down the Well of Entry. It was a game to them, too-though one with far greater rewards if they succeeded, and far deadlier consequences if they failed. Yet Darien needed to find one to whom Undermountain was not merely a game. He had to find one who could brave the deadly depths like no other had before.

It was time to start asking questions.

Rising, he moved slowly through the firelit common room, making certain he stayed fully concealed within his cloak and hood. Few gave him a second look. Travelers in disguise were hardly an unusual sight at the Inn of the Yawning Portal. Sitting alone in a corner was a bent-nosed man in a travel-stained leather jerkin. He looked like a suitable candidate. Darien hesitated only a moment, then swiftly sat down opposite him.

Bent-Nose looked up, his beady eyes hazy with drink. "What in the Abyss do you want?"

"Your advice," Darien replied smoothly from the shadows of his hood.

The other man grunted in surprise. Clearly this was not a request he received often.

"You see, I have lost something," Darien continued in a low voice. "Something of great value to me."

At this, interest flickered across Bent-Nose's weathered face. "How valuable?"

"Very."

Bent-Nose scratched his scraggly beard. "And I suppose you're looking for someone who can find it for you."

From the purse beneath his cloak, Darien withdrew a gleaming gold coin and placed it on the table. The man eyed the coin greedily.
