LEGION INTERNAL REPORT

AFTER-ACTION REPORT

Operation Name: Black Current
Engagement: Siege of the Ankiol River
Location: Northern Reach, Princedom-held choke point
Date: [REDACTED]
Prepared by: High Command Analysis Division

1. Objective

Primary: Secure the Ankiol River extraction zone for continuous harvesting of raw Psyro-glass, per directive from the Nine.
Secondary: Eliminate entrenched Princedom defensive capacity in the Northern Reach to prevent counter-claims and ensure uninterrupted supply chain access.

2. Strategic Overview

The Ankiol River is a rare natural vein where raw Psyro-glass flows across open terrain. In solid phase (night cycle) it can be harvested and transported for industrial, medical, and weapons applications. In molten phase (day cycle) it becomes a highly corrosive, magma-like flow capable of destroying most materials on contact.

Princedom forces had seized and fortified the river’s narrowest choke point, ideal for mining and shipment control, constructing:

Cliffside entrenched artillery and lance positions

Layered barricades built from reinforced hull plating

Thermal-shielded trench systems with overlapping fields of fire

Direct assault risked high Legion casualties and damage to the resource itself. Engineering Corps proposed environmental weaponization of the river’s molten phase.

3. Execution Plan

Phase I – Night Operations

Time: 2100–0200 hours

During solid phase, Legion engineers infiltrated upstream and cut into the riverbed at a natural narrowing.

Installed reinforced containment barriers anchored into bedrock, constructed from ceramic-composite armor resistant to initial melt-phase temperatures.

Phase II – Reservoir Formation

Time: 0200–1100 hours

As sunrise transitioned the Psyro Glass to molten phase, flow was trapped behind the upstream barrier.

Reservoir volume increased under thermal expansion, with surface temperatures exceeding +1,300°C and core readings topping +1,800°C.

Seismic monitoring confirmed barrier stability until maximum destructive potential was achieved.

Phase III – Weaponization and Release

Time: 1100 hours

Shaped demolition charges breached the barrier.

A molten surge of raw Psyro-glass, 14 meters high at breach point, flooded the valley at an estimated 21–27 km/h.

Contact effects:

Barricades and armor liquefied in seconds.

Thermal undermining destabilized cliffside artillery positions.

Trenches sealed into black glass pits, entombing personnel.

Princedom defensive capacity eliminated within minutes.

4. Duration of Engagement

Total operational time: 5 hours 47 minutes
Active combat after release: < 40 minutes
Legion casualties: 0 fatalities, 5 thermal injuries (engineering crews)

5. Post-Engagement Observations

Entire choke point encased in fused black Psyro-glass.

Princedom equipment and personnel integrated into the hardened surface, unrecoverable without damaging resource integrity.

Affected stretch of river continues to shed glass particulates downstream; hazardous to unshielded mining operations.

No surviving Princedom forces in sector.

6. Strategic Outcome

Nine’s directive fulfilled: extraction rights secured.

Princedom presence in Northern Reach eradicated.

Environmental weaponization confirmed as effective for similar riverine resource zones under contested control.

7. Conclusion

Operation Black Current met all strategic and political objectives. The Nine’s material priority secured without protracted siege. Sector remains under Legion guard with immediate upstream control point established.

Filed and Sealed: By order of Legion High Command.
