Fernmirror Pool
Palakar Forest · Optional antidote site · The forest in the reflection
Below a fallen cedar rests a green pool, perfectly still despite the breeze moving through the ferns. Its surface reflects a forest brighter and healthier than the one around you: unscarred bark, lush roots, and a canopy free of blackened branches. Beneath the reflected leaves, thin golden threads pulse in the real water, and several dark, round shapes cling to submerged roots.
GM — The Unmoving Mirror
OPTIONAL ANTIDOTE SITE. Fernmirror Pool is a secondary seep connected to Silverrun Crossing through infected roots and wet soil. The blight holds the surface unnaturally still, preserving a deceptive image of the forest as it was before corruption reached this place. The reflection is a supernatural echo, not a portal, illusionary creature, or additional combat encounter. The blightwater beneath remains contaminated. Treating Fernmirror improves western containment, but the party does not need to spend a fourth Watercourse Neutralizer dose to complete the three primary water objectives.
Read the Reflection
A character who watches the pool notices that its mirrored branches do not move with the real canopy. As a pebble, stick, or breeze-disturbing object breaks the surface, the healthy image briefly fractures to reveal black rootlets beneath, winding toward the central blightnode. In the fractured reflection, buried roots seem to writhe against the wind. This is an atmospheric clue to the infection's underground reach, not a saving-throw effect.
Nature DC 18: The black-gold filaments mark a secondary infected root channel connecting Fernmirror to Silverrun. Left active, this seep could slowly recontaminate Silverrun even after its western intake is treated. On a critical success, the character traces the general convergence of the root channels toward the central blightnode and identifies the safest approach to the submerged intake. Players who inspect the visible roots cautiously can recognize contamination without drinking the water.
The Blightseed Pods — A Defensive Trap
Several baseball-sized seedpods cling to root strands below the fallen cedar. Their translucent black-sap skins are streaked with fine golden veins; needlelike seeds press against the membranes. These pods are defensive growths, not separate blightseed objectives. Do not require separate Watercourse Neutralizer doses for them.
The attached Blightseed Pod Burst — Simple Hazard 2 is the only active encounter threat here. Perception DC 18 (trained) reveals the swollen pods beneath the strange reflection. Nature DC 18 can detach the cluster or Survival DC 18 identifies a safe access point. Disturbing the cluster unprepared releases a 10-foot burst of needlelike seeds: DC 18 basic Reflex against 2d6 piercing damage, with sickened 1 on a critical failure. The cluster expends itself after bursting and does not reset. Careful characters can bypass it, work from another bank, or disarm it before handling the root intake.
Optional Objective — Neutralize the Secondary Seep
The infected root intake lies under the fallen cedar where the golden strands disappear into dark sediment. The players can safely sample the water, mark the pool for Cedar Court specialists, or spend one additional Watercourse Neutralizer dose to treat the secondary seep. Splashing neutralizer onto the mirrored surface does not reach the infection; it must contact the submerged living root intake.
Without pressure: Once the area is secure and the intake accessible, placing one dose takes 10 minutes with no roll. Under pressure: use the attached Neutralizer Placement — Fernmirror Pool challenge: Nature or Crafting DC 18 secures the dose in approximately 2 minutes. Failure costs time or repositioning; it does not automatically expend the antidote. Disabling the pod trap is not required if the party finds a safe route to the roots.
As the antidote reaches the roots, the gold in the water flickers and fades. The perfect image of the untouched forest breaks apart in widening ripples. For the first time, Fernmirror reflects the trees as they truly stand—scarred, wind-stirred, and still alive.
Consequences and Choices
If treated: The surface returns to ordinary movement, the golden seep recedes, and an important route for recontaminating Silverrun is interrupted. This does not destroy the central Stage 3 node.
If mapped but untreated: The party can report the site to Thornwatch for later treatment by Cedar Court specialists. This is an acceptable outcome, especially when the party carries only enough antidote for the three primary waters. The secondary seep remains active until someone returns to neutralize it.
Report the supernatural reflection, the hidden defensive pods, and the secondary root channel linking Fernmirror to Silverrun. Record Fernmirror: Treated or Fernmirror: Mapped for Later. Do not turn an optional fourth-dose objective into a mandatory obstacle to campaign progress.
This location uses the Watercourse Neutralizer, a custom field preparation for contaminated groundwater and infected root intakes. Use one watercourse dose per water site; a dose must reach the living feeder roots, not merely splash into open water. It suppresses the local contamination but cannot destroy an exposed infernal blightseed. The separate Blightseed Antidote treats seed cores directly and is not interchangeable. Treat all application timings and DCs here as scenario-specific skill challenges, not universal PF2e consumable rules.
