"In a hurry?"

"A great hurry," Obi-Wan said.

"The chosen one is not in his quarters?" Mace's tone carried both respect and irony, a combination at which he was particularly adept.

"I know where he's gone, Master Windu. I found his tools, his workbench."

"Not just building droids we don't need?"

"No, Master," Obi-Wan said.

"About the boy-" Mace Windu began.

"Master, when there is time."

"Of course," Mace said. "Find him. Then we shall speak. . and I want him there to listen."

"Of course, Master!" Obi-Wan did not disguise his haste. Few could hide concern or intent from Mace Windu.

Mace smiled. "He will bring you wisdom!" he called out as Obi-Wan ran down the hall toward the turbolift and the Tem ple's sky transport exit.

Obi-Wan was not in the least irritated by the jibe. He quite agreed.Wisdom, or insanity. It was ridiculous for a Jedi to always be chasing after a troublesome Padawan. But Anakin was no ordinary Padawan. He had been bequeathed to Obi-Wan by Obi-Wan's own beloved Master, Qui-Gon Jinn.

Yoda had put the situation to Obi-Wan with some style a few months back, as they squatted over a glowing charcoal fire and cooked shoo bread and wurr in his small, low- ceilinged quarters. Yoda had been about to leave Coruscant on business that did not concern Obi-Wan. He had ended a long, contemplative silence by saying, "A very interesting problem you face, and so we all face, Obi-Wan Kenobi."

Obi-Wan, ever the polite one, had tilted his head as if he were not acquainted with any particular problem.

"The chosen one Qui-Gon gave to us all, not proven, full of fear, and yours to save. And if you do not save him…"

Yoda had said nothing more to Obi-Wan about Anakin thereafter. His words echoed in Obi-Wan's thoughts as he took an express taxi to the outskirts of the Senate District. Travel time-mere minutes, with wrenching twists and turns through hundreds of slower, cheaper lanes and levels of traffic.

Obi-Wan was concerned it would not be nearly fast enough.

The pit spread before Anakin as he stepped out on the apron below the tunnel. The three other contestants in this flight jostled for a view. The Blood Carver was particularly rough with Anakin, who had hoped to save all his energy for the flight.

What's eating him? the boy wondered.

The pit was two kilometers wide and three deep from the top of the last accelerator shield to the dark bottom. This old maintenance tunnel overlooked the second accelerator shield. Squinting up, Anakin saw the bottom of the first shield, a huge concave roof cut through with an orderly pattern of hundreds of holes, like an overturned colander in Shmi's kitchen on Tatooine. Each hole in this colander, however, was ten meters wide. Hundreds of shafts of sunlight dropped from the ports to pierce the gloom, acting like sundials to tell the time in the open world, high above the tunnel. It was well past meridian.

There were over five thousand such garbage pits on Corus cant. The city-planet produced a trillion tons of garbage every hour. Waste that was too dangerous to recycle-fusion shields, worn-out hyperdrive cores, and a thousand other by- products of a rich and highly advanced world-was delivered to the district pit. Here, the waste was sealed into canisters, and the canisters were conveyed along magnetic rails to a huge circular gun carriage below the lowest shield. Every five seconds, a volley of canisters was propelled from the gun by chemical charges. The shields then guided the trajectory of the canisters through their holes, gave them an extra tractor-field boost, and sent them into tightly controlled orbits around Coruscant.

Hour after hour, garbage ships in orbit collected the canisters and transported them to outlying moons for storage. Some of the most dangerous loads were actually shot off into the large, dim yellow sun, where they would vanish like dust motes cast into a volcano.

It was a precise and necessary operation, carried out like clockwork day after day, year after year.

Perhaps a century before, someone had thought of turning the pits into an illegal sport center, where aspiring young toughs from Coruscant's rougher neighborhoods, deep below the glittering upper city, could prove their mettle. The sport had become surprisingly popular in the pirate entertainment channels that fed into elite apartments, high in the star-scrubbing towers that rose everywhere on the capital world. Enough money was generated that some pit officials could be persuaded to turn a blind eye, so long as the contestants were the only ones at risk.

A garbage canister, hurled through the accelerator shields, could easily swat a dozen racers aside without damage to itself. The last shield would supply it with the corrective boost necessary to compensate for a few small lives.

Anakin watched the flickering jump light on the tunnel ceiling with focused concentration, lips tight, eyes wide, a little dew of sweat on his cheeks. The tunnel was hot. He could hear the roar of canisters, see their silver specks shoot through the shield ports to the next higher level, leaving behind blue streaks of ionized air.

The pit atmosphere smelled like a bad shop generator, thick with ozone and the burnt-rubber odor of gun discharge.

The tunnel master twirled up to the exit to encourage the next team.

"Glory and destiny!" the Naplousean enthused, and slapped Anakin across the brace between his wings. Anakin stayed fo cused, trying to sense where the currents would be at this level, where the little vortices of lift and plunge would accumulate as they formed and rotated between the shields. Ozone would always be in highest concentration in the areas where the winds would be strongest and most dangerous. And for every volley of canisters, following a prearranged formation through the shields, another volley would soon follow, taking a precisely determined series of alternate routes.

Easy. Like flying between a storm of steel raindrops.

Anakin's fellow racers took their places in the tunnel's exit, jockeying for the best position on the apron. The Blood Carver gave Anakin a jab with his jet-tipped right wing. Anakin pushed it aside and kept his focus.

The Naplousean tunnel master lifted its ribbon-limb, the tip curling and uncurling in anticipation.

The Blood Carver stood to Anakin's left and closed his eyes to slits. His nostril flaps pulsed and flared, filled with tiny sensory cavities, sweeping the air for clues.

The Naplousean made a thick whickering noise-its way of cursing-and ordered the contestants to hold. A flying mainte nance droid was making a sweep of this level. From where they waited, the droid appeared as a flyspeck, a tiny dot buzzing its way around the wide gray circumference of the pit, issuing little musical tones between the roar and swoosh of canisters.
