# Infernal Map of the War-Slough

## What the Characters See
As the infernal parchment unfolds, the ink immediately begins to shift and crawl across its surface. Rivers move. Roads twist. Entire landmarks drift slightly from where they were moments before.
Despite this impossible movement, the names of locations remain constant.
The map does not reveal distances or true geography. Instead, it seems to reveal only places that matter.
A faint smell of sulfur rises from the parchment, and the edges occasionally drip small droplets of blood that vanish before touching the ground.

## Read Aloud
> The parchment shudders in your hands.
>
> Crimson lines creep across its surface like veins beneath skin. Entire roads slowly change position, while mountains bend and rivers split apart.
>
> Yet the names remain fixed.
>
> The Crystal Battlefield.
>
> The Forgotten Trenches.
>
> The Choir of the Forgotten.
>
> Pillar of Skulls.
>
> The Largest Ichor Lake.
>
> No scale exists. No measurements are marked.
>
> A sentence appears briefly at the bottom of the map before fading again:
>
> ***"Hell remembers destinations, not journeys."***

# Infernal Map Mechanics
The map is not a conventional map.
## Fixed Information
The party always knows:
- The names of major locations.
- Which locations connect to one another.
- Which routes eventually lead toward the Largest Ichor Lake.
The party never knows:
- Exact distances.
- Travel times.
- Which route is safest.
- What dangers lie ahead.
---
# Choosing a Route
Whenever the party reaches a location, they may choose any visible connecting path.
Each path represents a **Travel Segment**.
During each Travel Segment:
1. Roll for encounters.
2. Apply environmental hazards.
3. Allow roleplaying scenes.
4. Present temptations or discoveries.
Distances change constantly.
A path that once took hours might later require an entire day.
---
# Crystal Battlefield (Starting Area)
The party begins at:
## [[The Crystal Battlefield]]
Visible routes lead toward:
- [[The Forgotten Trenches]]
- [[The Field Hospital]]
- [[Shattered Redoubts]]
The players may choose any route.
---
# Travel Segment Procedure
For each segment:
### Step 1: Navigation
Choose the next destination shown on the map.
### Step 2: Roll 1d6
| d6 | Result |
| --- | ------------------------------------------------------------------------------------------------------- |
| 1 | Combat encounter |
| 2 | Environmental hazard |
| 3 | Infernal temptation — see [[Placed Temptations by Layer]] or [[Random Temptations (d12)]] |
| 4 | Lost souls or roleplaying scene |
| 5 | Strange discovery |
| 6 | Uneventful travel |
### Step 3: Describe the Landscape
Emphasize:
- Endless battlefields.
- Rusted war machines.
- Rivers of demon ichor.
- Bones protruding from the mud.
- Distant sounds of war that never cease.
---
# Special Rule: The Map Changes
After each long rest, roll 1d4.
> ⚠️ **Reminder:** Long rests in the War-Slough also trigger a DC 20 Con save vs. [[Flesh Warping Table (d10)]]. Roll the map change *after* resolving any warping effects.
| d4 | Effect |
|----|---------|
| 1 | A route disappears temporarily. |
| 2 | A new route appears. |
| 3 | Nothing changes. |
| 4 | Two destinations swap positions on the map. |
Only the destinations remain constant.
---
# Reaching the Largest Ichor Lake
No matter which routes are chosen, all paths eventually converge upon:
## [[The Largest Ichor Lake]]
Deep beneath its blood-red waters lies the resting place of Brother.
And something else waits there.
# War-Slough Encounter Ideas
*Chains of Asmodeus*
The War-Slough is a realm where ancient battlefields never truly died. Trenches, ruined war machines, and rivers of demon ichor still echo with the memories of soldiers who never realized the war ended.
> **On short or long rests**, also roll on [[War-Slough Random Encounters (d6)]] in addition to any homebrew encounters below.
> **Demon Blood Mechanic:** After 1 hour in the War-Slough, DC 15 Con save or roll [[Flesh Warping Table (d10)]]. Same save after short rests; DC 20 after long rests.

Combining their memories reveals the password required to open the vault beneath the largest ichor lake.
---
