"The cloakers are going to have ample time to spring an ambush, with all that noise you're making," Cavatina warned her.

Thaleste was breathing hard from her exertions. Her face darkened in a blush. "My apologies, Mistress."

"Dark Lady," Cavatina corrected. "There are no matron mothers here."

"Dark Lady. My apologies."

Cavatina accepted the apology with a nod.

Eventually, they reached the spot where the cavern ended. The ceiling was low enough that Cavatina could have touched it. A faint breeze issued from a crack above her head. A narrow chimney, barely as wide as her shoulders, twisted up to the surface. She watched as Thaleste peered up into the opening.

There was movement inside the chimney-a flutter of wings. Thaleste shrieked as something small and black burst out of it. Cavatina, who had started to draw her sword even as Thaleste flinched, slid it back into its sheath. She stared at the creature as it flew away, squeaking.

"A bat." She sighed. "The next time something comes hurtling at you, Thaleste, try drawing your sword or casting a spell." She nodded at the chimney. "Now check the glyph"

Thaleste, blushing, murmured a prayer, casting a detection spell. Just inside the chimney, a glyph sprang into luminescence, sparkling like the light scattered by a diamond. Frowning in concentration, Thaleste studied its outlines, her finger tracing through the air in front of it.

"A songblast glyph," she announced at last, letting the glow fade. "Untriggered. Nothing evil has passed this way." Her shoulders relaxed a little as she said this.

"Unless it was ethereal," Cavatina reminded her.

The shoulders tensed again.

"Fortunately, the ability to assume ethereal form is something that few creatures-and only the most powerful spellcasters-are capable of," Cavatina continued. "And those that are capable of ethereal travel have no need for entrances like this one. They can pass through solid stone."

Thaleste swallowed nervously and glanced at the wall next to her out of the corner of her eye.

"The walls here are thick," Cavatina assured her. "Any spellcaster out on an ethereal jaunt would materialize inside solid stone long before reaching this spot."

Thaleste nodded.

"We're done here," Cavatina said. "Let's go back."

As they made their way back along the winding corridor they'd just traveled, Cavatina once again saw Thaleste startle. "Have you spotted something, Novice?"

Thaleste pointed at the ceiling. "A movement. Behind that broken window." She gave her mentor an apologetic smile. "Probably just another bat."

Cavatina chastised herself for having missed whatever Thaleste had just spotted. She should have been paying more attention. Then again, Thaleste was a nervous one. She'd only occasionally ventured outside the walls of her residence in Menzoberranzan. Her trip to Skullport had been an act of desperation. Eilistraee only knew how Thaleste had managed to survive as many decades as she had inside the City of Spiders. She was prone to seeing monsters in every shadow.

Even so, Cavatina drew her sword. The temple's battle-mistress had given specific orders to those on patrol. Any monster, no matter how small a threat it posed, was to be killed. The caverns the Promenade had recently claimed must be kept clean of vermin, and there were protocols to be followed. The use of silent speech during alerts, for example.

Stay here, Cavatina signed to Thaleste. I'll investigate. Cast a protection upon yourself, just in case.

Shouldn't I come with you?

No. The last thing Cavatina needed was a novice getting in the way of a hunt, and even if it turned out to be a cloaker up above, it would all be over in a few moments.

As Thaleste hurriedly whispered a protective prayer, Cavatina spoke the word that activated her magical boots. They lifted her into the air toward the window the novice had pointed at. The ceiling was perhaps a hundred paces high, and the window was one of those that had fallen away. Only a few jagged shards of clearstone hung from a hole that gaped a dozen paces wide. As Cavatina levitated toward it, a palm-sized fragment of clearstone dislodged from the remains of the window frame and fell, shattering to pieces on the stone floor below. Thaleste flinched away from it, her sword shaking in her hand.

Cavatina smiled as she rose toward the hole in the ceiling. Something was inside the room above. She gripped Demonbane in both hands, adjusting her grip on the worn leather of its hilt. Whatever it was, she was ready for it.

The window opened onto what had once been a grand hall. Pedestals along each wall held stone busts of those who had once inhabited the noble manor. Several of the busts had fallen and lay in pieces on the floor, but others had survived. A dais at one end of the room had probably once supported a throne. Behind the dais were the remains of a mosaic, most of its tiles long since fallen out. Enough remained, however, to show drow kneeling in submission before an altar, though the object of their veneration was indistinguishable. Side passages led off from the left and right.

All this, Cavatina took in at a glance. To all appearances, the room was as empty as any other in this area, but appearances could be deceiving. She twisted as she rose through the window, pushing off from what remained of the sill. Another piece of clearstone fell-something else for Thaleste to flinch at. As Cavatina drifted toward a more solid piece of floor, she sang a prayer. Divine magic surged out from her in a rippling circle, filling the room. If whatever was in here with her was invisible, the magic that cloaked it from sight was about to be purged.

The creature was revealed in mid-leap: a spider the size of a large dog, its spindly legs twice as long as Cavatina was tall. It came at her with its fang-tipped jaws distended, its mouth trailing drops of saliva that sparkled like golden faerie fire.

Cavatina slashed at the creature as it hurtled toward her, but the spider twisted in mid-leap, avoiding the blade. A slash that should have cleaved its body in two instead merely sliced off a couple of the bristles protruding from its cheek. Odd, that the spider had twisted its head toward the sword-it almost seemed to be trying to bite the weapon.

The spider landed on a wall and immediately flexed its abdomen toward her. As its spinnerets opened, Cavatina flung out her left hand and shouted Eilistraee's name. A shimmering, crescent-shaped shield sprang into being in front of Cavatina just in time to block the web the spider shot at her. The magical shield shuddered as the webs struck, then slowly sagged to the floor, weighed down by a mass of glowing golden webbing. Cavatina dispelled the shield, letting the sticky tangle fall.

She attacked. Releasing Demonbane, she sang a prayer that sent the sword dancing through the air toward the monster-a feint that would allow her to mount a second attack. She expected the spider to shy away from the blade, but instead the monster watched, unmoving, as the sword, directed by Cavatina's outstretched hand, wove through the air toward it. The spider sprang from the wall, directly at the sword. Twin fangs scissored against the metal. The spider sailed past Cavatina to land upside down on the ceiling, the sword between its fangs. Then it began to chew, as if savoring the taste of the blade.

Belatedly, Cavatina realized what she must be facing. "A spellgaunt!" she cried. She yanked her hand back, trying to wrench Demonbane from its jaws, but they were locked around the sword. The spellgaunt stood utterly still for a heartbeat, a dribble of sparkling drool sliding out of the corners of its mouth. Then it spat the weapon to the ground. The sword hit the floor with a dull clank. It landed next to Cavatina's foot, its midpoint dented with a neat row of tooth marks.
