But she was not alone here. The empirium was all around her—brushing against her mind like tendrils, reaching for her, calling to her.

Her mind focused and clear, her lungs burning, she pushed out with her thoughts, moving the water away from her body until she was surrounded by a hair-thin shell of air.

It held, but it wouldn’t forever. Already she could feel the shell cracking, the weight of the waves pressing down on it as though against a thin pane of glass. A dull ache pulsed through her muscles. Her mind stretched and shifted like someone had reached into her skull and was reshaping the deep, dark place behind her eyes.

Your power is a miracle, Rielle, said Corien, his voice tinged with awe. I don’t understand it. Help me understand.

Rielle kicked hard and dove deeper.

The first item was easy:

A three-pronged trident head, sharp-tipped and silver, lying in a cluster of seaweed on the ocean floor.

Rielle kicked her way down, the pressure of the storming water making her ears throb. She grabbed the middle prong, and her palm lit up with pain. Her blood clouded the water; the shell around her body wavered.

Rielle recalled the story of Saint Nerida in the final battle at the Gate—how she had used her trident to impale the angel Razerak through his gut. His scream was loud enough that the sea birds along the northern Celdarian coast had dropped dead from the skies.

Focus, Rielle, she told herself, furious that she’d grabbed the prong without thinking. But then the sight of her own hand grasping the trident head gave her a burst of inspiration.

The people above, waiting for her to drown, would remember the stories of Saint Nerida too.

Rielle pushed herself off the seabed, kicking hard until she burst out of the water and thrust the trident head high into the air. Sheets of rain, thrown from a sky churning with clouds, slapped her cheeks.

Light shone down upon where Rielle bobbed in the waves. Acolytes from the House of Light cast bright beams of sunlight from the cliff tops.

Rielle turned her face up to the warmth, and once the crowd saw her—triumphantly holding the first piece of the trident, her sliced hand bleeding down her arm—a roar of cheers exploded. And though her protective shell of air muffled the sound, Rielle heard enough to know the truth:

They hadn’t expected her to emerge after so long underwater. But now she had, and now…now anything was possible.

Rielle grinned and dove back down. Once underwater, her air shell constricted, twisting about her body like a rag being wrung out. She choked, her throat tightening. She closed her eyes and fought for enough calm to pray.

Grow us the fruit of our fields.

She opened her eyes, glared at the angry black depths.

Drown us the cries of our enemies.

She reached for the empirium.

Follow me.

Obey me.

Warmth snapped at her fingers and toes.

Was the empirium listening?

Her focus renewed, she swam, searching the murky water for clues. But she saw only churning silt and salt, the occasional flitting shape of a swimming creature.

Then a hulking darkness solidified in the watery shadows—a sunken ship, half submerged in shifting sand and glowing faintly from within.

It was worth a try.

Rielle swam closer. The dense current of the water moved ever faster, flinging her wildly through swirling eddies one moment and pushing against her as a solid wall the next.

Inside the ship’s cracked hull was an eerie, half-lit land. Luminescent pink barnacles clung to the walls and ceiling. She swam through the captain’s quarters, the galley, a storeroom choked with fish that darted away at her approach…

There. A twinkling light caught her eye.

A gemstone, fist-sized and an inky blue in the darkness, winked at her from the floor of the ship. Saint Nerida’s sapphire. It would fasten to the end of the trident’s staff.

Rielle grabbed the sapphire, slipped it into her pocket, then froze.

The shimmering, rose-colored light suffusing the ship was suddenly brighter than it had been a few moments before.

Slowly, Rielle turned, and her stomach clenched in horror.

The luminescent barnacles that had carpeted the walls, lighting her way, weren’t barnacles at all. They were jellyfish—a swarm of them, cat-sized and glowing pink with bright bruise-purple centers. Sizzling light zapped between the fuzzy ends of their tentacles.

Panicking, Rielle kicked to push herself away from them. Something sharp jabbed her leg from behind; she whirled around in the water.

They were surrounding her. Drifting closer, inexorably, as if attracted to her rising terror. One of them bumped against her arm; a piercing hot sting jolted her. Another found her temple, her bleeding hand. They swarmed, reaching. Knots of glowing tentacles blocked her view of the ship and the sea beyond it.

She forgot all her prayers and lessons and screamed.

The scream broke her shell of air; the water closed in around her, cruel and cold.

She realized the change too late and gasped, choking on the sea.

Desperation forced her to move. She swam, wild, clumsy, swiped the trident head through the jellyfish, felt the prongs pierce something thick and gelatinous. A tentacle wrapped around her ankle, her unhurt arm. She reached back with the trident and sliced through them, tugged herself free.

She pushed and clawed, the swarm’s angry lights cutting across her vision. She hoped her suit was offering her some protection, but already her vision was dimming.

Air. Air. Air.

She made it out of the boat, reaching desperately for the surface. Her feet were numb, clumsy. She couldn’t tell what her body was doing, just knew she had to get up, get up, get out—

She burst out of the water, coughing hard. A wave pushed her under. She flailed, flipped over, found a burst of strength, climbed back up. Sweet saints, the air was glorious, pure and cold in her aching lungs. The rain beat down on her. Another wave pushed her under, and another right after. She emerged again and looked around wildly. Where were the cliffs? Where were the sunspinner acolytes with their beams of light?

She saw blackness, shifting and growing all around her—no sky, no clouds.

The blackness, she realized with a burst of fear, was waves.

She dove, groped her pocket until she felt the hard gemstone, safely tucked away. She swam, searched the water, surfaced, and dove again. Were they watching her up above? Could they see her? She must have looked absurd—soaked and bleeding, suit torn, skin raised in angry welts.

You can do this, came Corien’s voice. His presence was calm and still. You can do so much more than this.

Can I? She wanted to sink to the seabed and cry. Unless you’re going to help me, leave me be.
