Ususi held out her right hand, concentrating on her trap-finding charm. She supposed far more powerful spells might lay bare all the dangers in a large radius, but she didn't know them. She hadn't gone out of her way to find such spells-she preferred to save her greatest strength for potent spells of blasting. If she roused some guardian demon, she was ready, she hoped, to send it back to whatever netherworld had spawned it. A few more paces, and the carvings on either side opened up to reveal a great, rounded chamber. Like the hallway, its periphery was heavily inscribed with images, words, and symbols. Even the ceiling was carved with thick clusters of sigils.

Ususi's breath caught when she spied the central feature of the chamber-a great stone annulus hovering unsupported in the air, measuring some ten paces in diameter. The ring slowly rotated, flipping end over end about once every two or three heartbeats. But the ring was not intact. A section of the hoop lay cracked and shattered on the floor. Two parallel creases appeared on the wizard's brow as she studied the debris. This could be a portal, perhaps leading into the Celestial Nadir, but it was damaged. First things first. Ususi renewed her concentration and scanned the room for traps.

She hadn't come this far so cautiously only to rush into the arms of a slicing blade or to be crushed beneath a ceiling block. The annulus itself could be a devious deception… but no. The room was clear.

Other than the rotating ring, one other exit presented itself. A flight of stairs led upward, the first upward set she'd discovered since entering the outpost. She wondered if it was an exit to the hills outside. It would wait. Ususi stood before the annulus.

Inscriptions crowded the stone circle, many unreadable. One symbol was clear immediately-a ring within a ring, the interior circle slightly off center-one of the symbols associated with the Celestial Nadir! The wizard drew the keystone from beneath her jacket. She held it forth, presenting it to the annulus. As Ususi handled it, the stone flickered and brightened, giving off a glow all its own. Ususi paused. Again, she noticed the hazed darkness at the stone's core. She shook her head slightly, deciding to worry about that later. Ususi let her mind touch the stone, and through its interface, sought contact with the ring.

She sought referents, points of synchronicity, answering reflections-even the smallest connection would be enough for her to try to gain control of the ring and force it open. Assuming it led to the Celestial Nadir. And if it was not broken beyond repair. But no.

"Four dooms and damnation!" she yelled. The annulus was dead. If it had ever been a portal, its functions were stripped. Only residual magic elevated it above the floor. A sudden thud shook her from her anger. Ususi whirled and stared. The light of her delver's orb sent feral shadows fleeing across the chamber. The sound had come from somewhere back along the way she'd traveled. She'd either missed a guardian, and it had roused from agelong quiescence to chase her down, or something or someone else had entered the buried outpost from the exterior. The wizard cursed herself for not securing the entry. Either way… Ususi touched the orb that hovered at her brow and its light died. The radiance of the keystone trickled away, too, as she hung it around her neck, under her jacket. The wizard didn't need light to trace her steps back over her course. She closed her eyes in the darkness and invoked a spell of clairvoyant vision. Beginning with the hallway where the two ancient emperors locked eyes for lost ages, Ususi's wizard sight bloomed, a window of seeing. Through her dark window, everything was blurred and colorless. Details faded and distances were hard to discern. She traced her path, pushing her vision down the inscribed hall and into the square room with the pool of iridescent liquid-water with an enchantment against evaporation.

The chamber was as empty as she'd left it. Farther yet, beyond the pool room, she found a bright red band of warning dye painted at neck height along the narrow passage. Something moved down that passage. It was… what was it? Identification was difficult because the image was blurred-it degraded the farther she forced it along. Whatever it was, it kept low, beneath the warning red stripe she'd placed on the wall. The figure used Ususi's system to its own benefit! She realized she'd marked a trail leading directly to her location. The wizard tensed but concentrated all her faculties on sharpening the clairvoyant image. A human? A man, definitely, but his skin was pale and marbled, not unlike her own. His outfit was familiar. Ususi let out an involuntary hiss and abandoned the vision. A vengeance taker.

After all this time, Deep Imaskar had finally tracked her down. Ususi brushed her orb and light flooded the chamber. The vengeance taker was too close-he would see it! But her wizard vision was too slow and unreliable in an emergency. She had to see in order to escape. "Get up those stairs," she whispered to the uskura. Ususi pointed to the other exit in the chamber. She dashed after her retreating pack. How had they tracked her into this ruin? They must have been looking for her for a long, long time. Ususi reached the archway and had one foot on the lowest step. "Hold, fugitive!" The voice was strong and authoritative. It was the voice of a vengeance taker. It was a voice accustomed to its commands being followed, and for good reason. Ususi darted up the narrow stairwell. The steps were high, shallow, and dusty. She gasped for breath, but the air seemed to have fled the stairway. She slipped and fell on the steps, catching herself with one hand but taking half her weight on the other shoulder. A cry of pain escaped her lips, like a sob. Her mind twirled, images of vengeance takers she had known and stories she had heard of their retribution causing tumult in her mind. She was panicking! This was not her. Ususi Manaallin did not panic. Ususi grasped the edges of her fear, wrenched it into halves, and cast its husks aside. She was a wizard, trained by the Cabal of Purple. A single taker would not bring her down, she vowed. She scrambled to her feet and turned to face down the staircase. Better to confront your enemies than to suffer their attacks at your back, she knew. She counted herself lucky his attack hadn't already sprung. Then she heard a strange, reverberating pulse.

It was a sound like-yet unlike-the noise of some of her own spells when she cast them-a hum like a rushing torrent heard in the rainy season, mixed with the high-pitched harmony of forlorn, tolling bells.

The noise halted as instantly as it had begun, leaving behind silence, the smell of ozone, and a glow of glittering, white reflections that patted at the bottom of the stairs. The vengeance taker must be casting preparatory spells, readying his advance, she thought. Takers were moderate-ability sorcerers, after all-magic was part of the deadly training they received. Yet it was no spell she recognized.

"Fugitive… Manaallin!" It was the voice of her pursuer. Yet his tone had shifted slightly. Ususi maintained her silence, waiting for the attack. Her hands were poised to release a torrent of destructive curses. "Ususi Manaallin-if you can hear me, I pray you pause. I haven't come so far to lose you now." The voice sounded strained, and its authoritative blare was dulled-by what? Ususi couldn't tell. He was crafty enough not to poke his head through the arch and look up the stairs-he must have sensed Ususi's spells ready to strip his flesh and worse. So instead, he seemed to be trying to draw her into the arms of his attack. Ususi yelled down the corridor. "It's a standoff, Vengeance Taker! I will not walk into your trap, and if you follow me up these stairs, it'll be the last act you ever take!" A chuckle answered her threat. The voice said, "Will you pretend you did not leave this painful blaze to catch me?" Another chuckle, somehow self-deprecating. Ususi didn't have the first clue what the taker was talking about. "Explain," she said. "Your ploy succeeded-you were clever in identifying every dormant trap in this molding ruin with your red dye-but even cleverer in failing to mark the very last one."
