Chapter Thirteen: The Sentry
The guard post on the north ridge was a stone hut with a sloped roof and a door that didn't close all the way. Inside: a stool, a logbook, a signal horn hung on a nail, and a lantern that burned with the enthusiasm of a candle that had given up on life.
Jax, the senior watchman, walked Zack through the basics with the flat efficiency of a man who had explained this forty times and expected to explain it forty more.
"Logbook. Write what you see. The patrol pattern runs east to west along the ridge, a quarter-mile each direction, back to the post. The signal horn is for emergencies. Three blasts for Gloomspawn, two for fire, and one for anything else."
"What counts as anything else?"
"If you have to ask, blow the horn." Jax scratched his jaw. "Mostly, you watch the trees and don't fall asleep."
Inspiring. The recruitment speech writes itself.
Jax left. The night folded in around the post.
Zack sat on the stool and looked north. The ridge dropped into dense forest that ran for miles before hitting the Sunspire border. Stars scattered above, sharp and cold. No moon tonight. The darkness had layers.
He let the void reach outward.
The sensation was like opening a fist he hadn't realized was clenched. The cold place behind his sternum expanded, and his awareness pushed past the walls of the guard post and into the surrounding landscape.
The village behind him registered as scattered points of warmth. Dim embers in sleeping houses. The faint glow of Aether flowing through walls and foundations, the residual energy of a settlement built on living ground. Warm. Safe. Familiar.
The forest was different.
Life pulsed through the canopy in layers. Trees blazed green. Animals flickered as bright sparks, darting and pausing and darting again. Insects formed constellations of tiny heat. The Aether wove through everything in dense, healthy currents.
But deeper in, the pattern broke.
Three spots. Cold. Knotted. The Aether currents bent around them the way water bends around stones in a stream. No life grew at their centers. No insects flickered. No animals approached. They sat in the forest like wounds that refused to heal, pulling energy inward and giving nothing back.
Corruption nodes.
Three of them. Quarter mile in, half mile in, and one further out. Northwest. The nearest one sits right where Burrel's patrol map marks "inactive disturbance." Inactive, my foot. That thing is eating the forest around it.
He mapped their positions. Fixed them in memory the way a sailor fixes the location of hidden reefs. The void in his chest stirred as it registered the nodes, and the stirring carried a flavor he didn't like. Hunger. Recognition. These cold spots operated on the same principle he did. They drained.
We're related. The corruption and me. Same mechanism, different scale. That's not a comforting family tree.
He turned his attention to something smaller. A birch tree stood twenty feet from the post, its trunk glowing with gentle green Aether. Healthy. Unremarkable.
He reached for it. Not the full pull he'd used on the weeds. A thread. A single, microscopic filament of thermal energy, drawn so slowly the tree wouldn't register the loss.
The warmth trickled into his palm. Faint. A candle's worth of heat absorbed over thirty seconds. The birch's closest leaf cooled by a fraction of a degree. It didn't yellow. Didn't wilt. Just dimmed, the way a lamp dims when the oil runs low.
He released. The leaf recovered within minutes, the Aether current refilling what he'd taken.
Control. Micro-siphoning. Take so little the source doesn't notice. If I can do this at scale, I can draw energy without leaving a trail of dead plants behind me.
He practiced for an hour. Pull. Hold. Release. The rhythm became meditative. Each draw refined his control, thinned the connection, reduced the footprint. By the tenth attempt, the leaf didn't dim at all.
Near midnight, the forest rippled.
Not a physical movement. A pulse in the pattern. One of the corruption nodes, the nearest one, flickered. The cold knot at its center contracted and expanded in a single sharp beat, like a heart skipping.
Zack's hand went to the horn.
He waited.
The ripple didn't repeat. The node settled back into its slow, steady drain. The forest around it held still.
One ripple. One data point. Not enough to blow the horn. Not enough to report. But something just moved inside that knot. Something that wasn't moving before.
The ring pulsed cold. The voice entered his skull, quieter than before. Teaching mode.
"Where the Paths are broken, the world sickens. That sickness spreads through submerged channels. Old energy flows beneath the soil, remnants of the First Path's architecture. The corruption follows those channels the way water follows cracks in stone."
Submerged channels. Under the ground.
"It attracts things. Gloomspawn are drawn to corruption the way flies are drawn to rot. A sentry who can sense the nodes would be valuable. A sentry who can sense them without anyone knowing how would be invaluable."
So I'm a secret weapon disguised as a night watchman. My career trajectory is really something.
The voice faded. The ring's cold settled to a low hum.
Zack wrote in the logbook. "Quiet. No movement." He did not mention the corruption nodes. He did not mention the ripple. He did not mention the submerged channels or the voice in his ring or the fact that he could sense life and death across a quarter-mile radius.
Some things belonged in logbooks. Other things belonged in the locked room behind his sternum where the void lived.
He leaned back on the stool. The forest hummed with layered energy. The stars turned overhead. His shift was half done.
Then something new brushed his awareness.
Not from the nodes. From deeper. Past the three cold spots, past the healthy forest, from somewhere in the deep north where his perception frayed at the edges.
A flicker. Observation. Cold, patient interest directed at him with the precision of a blade laid against skin.
The presence recognized the void in him. He felt it the way he felt his own heartbeat. A mutual awareness. Two empty things acknowledging each other across the dark.
That's not corruption. Corruption is mindless. Hunger without thought. This thinks. This watches. This chose to look at me right now, at this moment, and it knows what I am.
The presence lingered. It studied him the way Liddy had studied his knuckles. Collecting. Assessing. Then it withdrew. Sank into deep water. Gone.
Zack's fingers tightened around the horn. He did not blow it. There was nothing to report. A feeling. A suspicion. The kind of evidence that got a Husk laughed out of a guard post.
The ring bit into his palm.
"You were observed."
I noticed.
"Not by corruption. By something that thinks. A fragment. A servant of one." The voice paused. The pause was longer than any it had taken before. "You are not the only heir stirring. This changes the calculus."
Changes it how?
Another pause. When the voice returned, the frost in it had deepened.
"The paths of heirs often cross in blood."
