The old storehouse was damp, dusty, and smelled faintly of dried herbs and forgotten things. It was also, thankfully, isolated. For the next twenty-four hours, Kenji barely slept, fueled by dried fruit, water, and a growing sense of urgency. Lyra, true to Elara's word, acted as his tiny, glowing sentinel, occasionally bringing him berries or just perching on a rafter, watching him with a mixture of concern and awe.
His primary task was to modify his Aetheric Perimeter Early Warning System (APEWS) sensors. The original "Firefly" motes were designed for airborne or surface-level Blight Aether signatures. Detecting subterranean Skitterers required a different approach.
// Project Update: APEWS v0.1.2 - Codename: 'Earthworm Network' // Modification Focus: DAS (Distributed Aetheric Sensor) units. // New Functionality: // 1. Seismic Resonance Detection: Calibrated to identify unnatural, rhythmic vibrations consistent with mass burrowing activity. // 2. Subterranean Aetheric Anomaly Scan: Tuned to detect concentrated Blight Aether signatures moving beneath the surface. // 3. Inter-Sensor Triangulation: Basic algorithm to estimate origin and direction of subterranean threats based on input from multiple sensors. // Aether Cost per Sensor: Increased by 0.05 Units/hour (active scanning). // Deployment Strategy: Bury sensors at strategic points around the palisade perimeter, 0.5 - 1 meter deep.
He worked like a man possessed, his hands moving in the air as if manipulating invisible interfaces, his brow furrowed in concentration. He wasn't just writing code in his mind anymore; he was actively shaping and infusing Aether into the tiny sensor motes, tweaking their internal "structure," their resonance frequencies. It was like hardware and software engineering rolled into one, performed with an energy source he was still struggling to fully comprehend.

PROJECT: APEWS Sensor Recalibration ('Earthworm Network')
STATUS: COMPLETE (Sensors #DAS-S-001 through #DAS-S-020)
TEST RESULTS (Simulated):
- Subterranean Blight Signature Detection Accuracy: ~70%
- False Positive Rate (Natural Seismic Activity): ~15%
SYSTEM NOTE:
Further refinement and field testing recommended for optimal performance.
Consider algorithm enhancements for noise filtering.

He also started sketching out designs for more active defenses, should his "Earthworm Network" fail or prove insufficient. The memory of Greystone, of his weak Aether Shards, still stung.
// Concept: Aetheric Geyser Trap (AGT) - v0.0.1 // Principle: Pre-charge a localized underground area with unstable Aether. Trigger remotely or via APEWS alert. // Effect: Sudden eruption of Aetheric energy from the ground, designed to disrupt, damage, or repel burrowing Blighted entities. // Challenges: High Aether cost for pre-charging, risk of ground instability, precise targeting, potential for friendly fire if not carefully managed.
It was a dangerous idea, a "landmine" of sorts, but the Skitterers presented a unique threat that required unconventional solutions.
By the time Finn and his scouts returned two days later, looking even more grim than when they'd left, Kenji had managed to create and "plant" twenty modified sensors around Havenwood's perimeter. He'd done it under the cover of darkness, Lyra providing a faint, guiding light, his Aetheric Resonance Scan helping him avoid major roots or rocks. He was exhausted, his Aether levels hovering around 30%, but the first layer of his Havenwood_Defense_System_v0.1 was active.
Finn's report was dire. "They're moving fast, Elder. And there are more than we thought. Not just Skitterers. We saw… larger things. Like a moving hill of chitin and claws, burrowing with them. And the ground… it trembles where they pass."

PRIMARY THREAT IDENTIFIED: Blighted Brood Mother (Probable)
- Classification: Class Delta Entity (High Danger)
ASSOCIATED UNITS: Blighted Skitterers (Numerous)
- Classification: Class Epsilon Swarm
THREAT VECTOR: Mass subterranean assault.
- Coordinated attack likely.
- High potential to overwhelm existing defenses through sheer numbers.
ESTIMATED ARRIVAL (Havenwood Perimeter): 24-48 hours.

Elara listened, her face pale but her resolve unbroken. "Then we have little time. Martha, organize all able-bodied villagers. Arm them with whatever we have. Sharpen every spear, every axe."
Martha nodded curtly. "We'll be ready."
Elara then turned to Kenji. "Your… experiments, Kenji-san. Are they prepared?"
Kenji took a deep breath. "The early warning system is active. It should give us some notice if they approach underground. As for… other measures… I have some ideas, but they are untested and potentially dangerous."
"In these times, 'untested' is often our only option," Elara said. "What do you propose?"
Kenji quickly outlined his Aetheric Geyser Trap concept, emphasizing the risks. He also suggested reinforcing key sections of the palisade using his Aetheric Reinforcement script, a more reliable, if Aether-intensive, measure.
------------------------------------------------------------------------------
[SAI - System Log/Defense Recommendation]
------------------------------------------------------------------------------
PRIORITY 1: Palisade Reinforcement
- Rationale: Enhance existing static defenses. Lower immediate risk profile.
- Target: Gates, identified weaker sections.
PRIORITY 2: Aetheric Geyser Trap (AGT) Deployment (Limited)
- Rationale: High-risk, high-reward counter to subterranean threats.
- Deployment: Designated kill-zones outside immediate village structures only.
- Caution: Requires precise targeting and Aether management.
------------------------------------------------------------------------------
"Reinforce the palisade first," Kenji said, echoing his internal system. "Especially the gates and weaker sections. The traps… we can prepare a few at the most likely approaches, but we must be careful."
For the next day and night, Havenwood was a hive of desperate activity. Villagers, their faces tight with fear but also a grim determination, worked tirelessly. Kenji, pushing his Aether regeneration to its limits with Lyra's help (she seemed to be able to channel small amounts of ambient Aether to him, a discovery that was both surprising and a relief), focused on the palisade. He moved along the wooden walls, his hands glowing faintly as he "injected" Aetheric reinforcement matrices into the timber, making the wood denser, more resilient.

He also, with the help of Finn and a few trusted villagers Martha assigned to him, prepared three Aetheric Geyser Traps in the open ground beyond the north gate, the most likely direction of the subterranean attack according to Finn's scouting. He "buried" concentrated charges of unstable Aether, marking the trigger zones with innocuous-looking stones, his interface linked to their activation.
As the second dawn approached after Finn's return, an almost palpable tension hung over Havenwood. Every villager was armed, every eye scanned the horizon, every ear strained for the slightest tremor in the earth. Kenji stood on the narrow walkway atop the north gate, Lyra a nervous spark on his shoulder. His "Earthworm Network" display was active in his vision, a series of green dots representing his sensors. So far, all quiet.

He was the architect of this desperate defense. He'd written the code, laid the foundations. Now, all he could do was wait for the system to be tested. And pray his gambit wouldn't lead to a catastrophic crash.
