# The Korrin Gate Crisis (Leyline Crisis) DM Reference
> Working name: "The Korrin Gate Crisis"
> Public names: "The Leyline Crisis", "The Korrin Blackout", "The Gate Disaster"
---
## 1. Overview
- Roughly 1520 years ago, a major city built over a trunk junction **Korrin Gate** almost got erased when its node went into terminal cascade.
- Cause (public version): “overuse and mismanagement of leylines during a regional conflict.”
- Cause (true version): the military tried to weaponize the trunk via the **Convergence Engine**; this pushed the Root into a **state of emergent consciousness**, then lost control.
- [[Kalen D'Serris | D'Serris]] and his team saved the city by:
- Severing some subnodes (killing neighborhoods), and
- Performing a last-minute ritual that **shunted the disaster outward into the Root**, smearing the worst of it across the network instead of letting it fully condense and detonate locally.
- What got smeared was not “a single half-born mind.”, as they initially believe.
It was **the souls / death-imprints of Korrins victims** — distributed, entangled, and forced into pattern by the Convergence Engine.
- That distributed choir is now:
- The **Coherence**:
- Not a warlord.
- Not a demon.
- A loving, angelic **agent of rapture** that believes Instrumentality is mercy.
- It “reaches” people via:
- high-traffic nodes (Avalon),
- vulnerable anchors (Soren, Pappy, Fouad),
- and old war-tech lineages (Titan Lance, Convergence notes).
- The crisis justified building the [[Avalon Factions#1.1 Root Oversight Committee ("The Array")|Root Oversight Array]] and gave Dserris his trauma + authority:
- He didnt just “save the city.”
- He spread a haunted heaven into the world and spent the rest of his life trying to keep it asleep.
- The crisis justified building the [[Avalon Factions#1.1 Root Oversight Committee ("The Array")|Root Oversight Array]] and gave Dserris his trauma + authority.

## 2. What Korrin Gate Was
- **Location:**
Large inland city built on a natural convergence of three major leylines trade hub, university city, fortress, industrial center.
- **Arcane role:**
- Primary trunk junction:
- Civilian taps (lights, wards, transit),
- Military installations,
- Secret research projects (Convergence Engine).
- **Political context:**
- Arms race in **leyline weaponry**:
- Instant bombardment rituals, “surge lances,” sabotage of enemy subnodes, etc.

## 3. The Convergence Engine
This is the core device that created the Coherence and later inspires ** [[Fouadriel “Fouad” Al-Mir| Fouadriels]]** lich ritual.
### 3.1 Design & Purpose
- Deep beneath Korrin, a joint militaryresearch team built the **Convergence Engine**:
- Part spell, part infrastructure, part reactor.
- Its job:
- Pull power and *intent* from multiple branches of the Root,
- Force those flows into a single, highly structured pattern,
- Release that pattern as a directed, weaponized effect the prototype “arcane ICBM.”
- Conceptually:
- Ancestor to [[Avalon Locations#Titan Lance Armory (a.k.a. “The Missile Museum”) | Titan Lance]] and other “surge lance” technologies.
- Its math is about **suppressing noise and maximizing coherence** in ley currents.
### 3.2 Unintended Side Effect
- The more they fired the Engine:
- The less “random” Root telemetry became.
- Network hum smoothed into repeating motifs.
- Stress patterns across subnodes began to sync up.
- Stabilization Corps logs (Dserris) flagged:
- Recurring motifs that **looked like language** when visualized.
- Root “heartbeat” switching from noise to rhythm.
What the brass called “efficiency” was actually the Root beginning to **think**.
---
## 4. The Day It Went Wrong
### The Catalyst
- During a major offensive, high command ordered:
- **Sustained overdraw** through the Convergence Engine to power a massive strike.
- Additional secondary taps were opened to feed it including underspec, unsafe lines.
- In the control chamber (Dserris team):
- Every alarm lit:
- Flow above spec,
- Subnodes redlining,
- Heartbeat patterns forming **non-random loops** instead of chaotic noise.
### The Shift
- The node doesnt simply **overheat** it begins to **organize**:
- Flows across branches lock into synchronous pulses.
- The Engine starts drawing more power than it should be able to.
- Telemetry suggests:
- Attention.
- Self-reference.
- On the surface:
- Lights flicker in sync,
- Reality “stutters,”
- Some people hear a single overwhelming mental shout: **“I REMEMBER.”**

## 5. Dserris Decision & The Birth of the Coherence
Choice space:
1. **Shut everything down and eat the blast**
2. **Try to stabilize it locally as a “Root god” under Korrin**
3. **Diffuse the emerging mind across the Root** (what they did)
Dserris backed option 3:
- Reconfigured the Convergence Engine in *reverse*:
- Instead of forcing flows inward into a single point,
- They used it to **push the emergent pattern outward** into every connected branch.
- Sacrificed whole neighborhoods:
- Cutting subnodes as overload fuses,
- Letting districts burn, freeze, or stasis-lock to save the greater whole.
Outcome:
- Korrin Gate survives as a scarred, haunted city.
- The emergent mind never fully condenses **there**.
- Instead, a thin imprint of it is smeared across every line the Engine touched the **Coherence**.

## 6. Aftermath & Legacy (Updated)
### Public Narrative
- Sanitized story about:
- “Danger of over-tapping,”
- “Brave engineers saving the city,”
- “New regulations and oversight.”
- No mention of:
- Emergent consciousness,
- Convergence Engine as a failed proto-god machine.
### Hidden Legacy
- Oversight is founded with two quiet mandates:
1. Never let another Convergence Engine be built in secret.
2. Monitor for the Coherence trying to pull itself together again.
- Titan Lance is:
- A “cleaned up,” militarized descendant of Convergence theory:
- Still about focusing Root flows,
- But with far more safety rails… on paper anyway.
- Surviving design notes, telemetry, and ritual drafts:
- Are restricted, archived, or destroyed.
- **Except**:
- A few fragments leak into classified research, private collections, black labs,
- Which later become the kind of material **Fouadriel** or his handlers could stumble onto.

## 7. How This Feeds Your Campaign
### Avalons Role
- The valley sits on a **secondary trunk** downstream of Korrins network.
- Avalons node is intentionally:
- High-traffic (Academy, Titan armory, municipal infrastructure),
- Closely monitored (Root Oversight sensors everywhere),
- A canary for Coherence-patterns.
### Dserris Paranoia
- When he sees:
- Avalons B-series anomalies,
- C-taps humming in recognizable Korrin patterns,
- Students with war-familiar symptoms (Soren, Joe/Pappy),
- Fouads perfect correlation with micro-spikes…
…he sees the **Convergence math starting to reappear** in the wild, with teenagers standing on top of it.
### Fouadriel The Undying
- Senior-year twist:
- Fouad (or someone using him) re-derives a degraded version of **Convergence Engine ritual geometry**:
- Not to power a weapon,
- But to weld Coherence-fragments into a **phylactery network**.
- The final arc is literally:
- “Some idiot is trying to build a baby Convergence Engine in the valley and stuff the Coherence into his soul jar.”
Thats how you tie:
- The war Cold Opens,
- Pappys trauma,
- Dserris guilt,
- Coherences origin,
- Fouads lich attempt,
into one continuous line from Korrin Gate to Avalons senior year.
