"Defenders!" Erelda shouted, her sword pealing in her hand as she pointed with it. "A breach. An ooze is-"
The floor in front of the tunnel rippled. The walls slumped. The defenders closest to that entrance shouted as their feet sank into mud, slowing their charge. The ooze bulged through the songwall, rupturing it, and a swirling, stinking fog roiled into the room. Priestesses collapsed, choking, as it engulfed them.
A Protector ran forward on a prayer-wrought moonbridge, her singing sword pealing a challenge. She hurled a bolt of twined moonlight and shadow at the monstrous ooze. It bored through the creature, popping several of its bulging membranes. But then a wave of energy rippled from the ooze and rushed back along the moonbridge in a wave of chaotic color. The Protector tried to leap from the bridge, but the energy reached her before she could spring. She disappeared. For a heartbeat, a rent remained in the place where she had just stood. A cacophony of sounds, colors, and smells poured out of it, flickering between sensations faster than the eye could blink. Then the rent sealed shut.
"By all that's holy," Erelda whispered. "Where did it just send her?"
The ooze was fully inside the Cavern of Song now. It looked like a collection of multicolored, inflated sacs, glued together with shimmering slime. These popped as the prayers the priestesses hurled ruptured them, then reformed. Triumphant shouts came from behind the creature. The instant it was fully inside the cavern, half a dozen fanatics came howling in after it, their tentacle whips flailing. A Protector cut one of them down even as he leaped into the cavern, her singing sword pealing victoriously, but the fanatic beside him shouted a prayer. Green slime flowed from his fingers and turned into a wave that smashed into the Protector, knocking her down. When it subsided, she was gone.
The ooze, meanwhile, pushed its shimmering wave of chaotic energy ahead of it. One of the novices maintaining the sacred psalm was engulfed by the energy and vanished, screaming. The other, a pale-skinned moon elf, quavered on. The few lay worshipers remaining in the cavern either fled, screaming, or raised their arms in desperate prayer.
"Defenders!" Erelda cried. "To me!" She sang a blessing, and a ripple of shadow-dappled moonlight pooled around her, bathing the defenders closest to her in its pure, cleansing light. The blessing would anchor them, and prevent the bubbling ooze from tossing any more of them into whatever hostile realms it had hurled the others.
One of the defenders couldn't reach Erelda in time, and went down under a fanatic's lash. The priestess next to Erelda retaliated with a holy song that crumpled the fanatic where he stood. Erelda herself fended off an attack by a ghaunadan who transformed himself into a walking purple ooze when she tried to cut him in two. She finished him with a prayer that flung him into a wall, splattering him to pieces.
A ragged cheer went up from the priestesses around her, and she realized her foe had been the last of the fanatics. Yet the bubbling ooze remained. Thankfully, it was smaller, reduced in size by the priestess's attacks. "Praise Eilistraee," Erelda gasped. "We will hold the temple."
She realized she could hear herself speak. For the first time in decades, the sacred song had faltered. "The Evensong!" she shouted. The priestesses next to her took up the hymn. With her sword raised, Erelda stepped forward to finish off the ooze.
The world flip-flopped. Up became down. Erelda tumbled, flailing, to the ceiling, together with the handful of defenders who had been standing next to her. She slammed into stone, and saw stars. She scrambled upright-the floor of the cavern reeled dizzily over her head-and realized the ooze had somehow distorted the natural laws of reality. She hurled a bolt of moonlight and shadow "up" at the ooze, but it didn't stop the thing. The ooze slithered over the statue of Qilue, fouling it. Then it disappeared down the staircase leading to the top of the Pit.
Erelda and the others fell. Erelda's wrist snapped as she landed, and pain flared. She rose, cradling the arm against her chest, and sang a hymn of healing. Without looking to see how the others fared, she clambered over the slime-fouled statue and ran to the staircase, shaking feeling back into her hand.
She ran down the spiral stairs two steps at a time, one hand on the inside wall to steady herself, the other tightly gripping her sword. She slipped, scrambled, sometimes tumbled down the steps, which glistened with the multicolored slime left by the creature as it squeezed its way down the narrow staircase. Always the monster was just around the bend. Just out of sight.
Gasping, Erelda at last reached the bottom of the staircase. She slipped on the final steps and tumbled into a cavern. Its floor was a bumpy field of broken stone: the fragments of the walls Qilue had collapsed to fill the Pit. The Protector who'd been stationed at the top of the Mound was gone. The ooze was just ahead, bubbling toward the statue of Eilistraee. The statue, made up of tiny chips of magic-suspended stone, was no longer moving. It would have halted its dance when the sacred song faltered. That it hadn't resumed its slow pirouette was a grim sign. Hadn't anyone survived above?
Erelda leaped, her sword flashing. It sliced through the ooze, severing one glistening sac after another. The ooze deflated-but as it did, a rush of multicolored energy rippled outward from it and struck the statue. Half of the stone chips instantly disappeared, and the rest were transmuted to mud that fell like dirty rain onto the spot where it had stood.
Erelda gasped. Her throat tightened. The seal on the Pit-gone!
The rubble where the statue had stood glowed with a purple light. Tendrils of violet mist seeped out through cracks between the stones. A feeling like ice slid into Erelda's gut as she realized what this meant. The breach at the bottom of the Pit had opened!
The rubble quivered. Something was rising upward through the Pit.
"Eilistraee!" she cried. She leaped over the deflated ooze and hurled herself, face down, atop the Mound. She couldn't fuse the rubble-only Lady Qilue could do that with her silver fire-but she could sing into being a blessing that would hold back whatever was rising out of the Pit, for a time. "At this time of darkness, I call down your light. Make holy this-"
Her song slowed to a dirgelike moan as the purple mist filled her lungs. The cavern was thick with the stuff; she could no longer see the walls. A tentacle erupted out of the rubble next to her, as thick as her arm and glistening with slime. It knocked her tumbling. She turned-slowly, slowly-and saw the eye at the end of the tentacle open gummily, releasing beams of bright orange light that lanced through the purple smoke. One of these struck her sword, which vibrated as if it had just clanged against an opponent's blade. Its song shrilled to a panic-filled wail, and the steel glowed red with heat.
Erelda grabbed the sword and struggled-slowly, slowly-to her feet, clinging grimly to her weapon. The leather wrapping the hilt smoked, and the tip of the blade grew white hot. Molten metal trickled down it, like wax from a candle, and dripped onto Erelda's hand. She screamed and dropped the weapon. It fell silent.
Determined not to fail her goddess, she resumed her hymn.
A second tentacle emerged from the portal, beside the first. A second eye opened. Erelda's mind raced at a speed her body couldn't keep up with. Eilistraee aid me, she pleaded. It's Ghaunadaur's avatar! It's escaping from the Pit!
She kept singing. Slowly. The hymn was almost complete. One final word…
A ray of orange light struck her in the forehead, filling her with a panic that exploded through her body like shards of ice. Her song turned into a scream. Then she crumpled in despair.
She'd failed. The Promenade was lost.
