Silverrun Crossing
Palakar Forest · Primary antidote site · Blightwater guardians
Silverrun Creek flashes between moss-covered rocks and the roots of ancient cedars before widening beneath a weathered timber bridge. Most of the water runs clear, but along the shaded western bank, a slick black film clings to the stones. Fine gold threads pulse among the submerged roots. From somewhere beneath the bridge comes a low, throaty clicking, followed by the splash of something slipping underwater.
GM — The Addictive Water
PRIMARY ANTIDOTE SITE. The western watercourse feeds root networks nearer the central Stage 3 blightnode. The infernal infection enters through the submerged root intake on the contaminated bank, not through the entire fast-flowing stream. Here the blightwater has acquired an unnaturally pleasurable, reassuring taste. Creatures that repeatedly drink it crave its sensation and become irrationally possessive of the source. The black sheen and gold filaments mark the infected intake.
Five River Devils (Creature 1 each) moved upstream from waters farther downriver. Their presence so far inland is unusual: having found the tainted water, they have remained to drink, and their dependence has turned the crossing into territory they defend with escalating aggression. They do not understand the infernal blight or serve its makers. They are dangerous, addicted guardians of the source, and they may retreat to drink from it even when fighting would be more advantageous.
Occupants — Five River Devils
- Two beneath the bridge: Concealed among submerged supports and shadows, these River Devils watch the crossing and threaten anyone trying to pass overhead or descend to the creek. Their longspears have 10-foot reach.
- Two in the shallows: These patrol the waterline and move between rocks and fallen trunks. They prefer to use the stream for mobility and cover, entering and exiting the water instead of standing in the open.
- One at the polluted intake: This creature returns obsessively to the blackened root channel, guarding the water with particular ferocity. It is the first to challenge anyone inspecting, sampling, blocking, or treating the infected roots.
The River Devils have swim Speed 35 feet, wavesense 30 feet, and 10-foot-reach longspears. Use their existing monster artifact for all statistics, attacks, Bloodletting, and Blood Frenzy. Do not grant them additional mechanical powers simply for drinking the water.
Behavior and Roleplaying
Before battle, the River Devils can be seen drinking repeatedly from the contaminated bank, ignoring the cleaner water nearby. One may gesture insistently for a trespasser or captive to drink, communicating with posture and simple sounds rather than speaking a language the party necessarily understands. A refusal, an attempt to collect a sample, or an effort to poison or purify their treasured intake can provoke a hostile response. Their protectiveness is stronger than their desire to pursue fleeing enemies: if the party withdraws well away from the crossing, the guardians generally return to their water.
A scaled head rises between the dark bridge pilings. Its jaws open in a warning hiss, but instead of striking, it dips its face into the oily water and drinks deeply. Another shape glides toward the blackened roots, clutching a long spear across its chest. As you approach the bank, both creatures turn on you with sudden, possessive fury.
Approach and Tactics
- Scout first: Observation from cover reveals figures beneath the bridge and in the water. A cautious party can learn that the River Devils return continually to the contaminated intake.
- The bridge: The timber crossing avoids entering the creek, but exposed travelers can be threatened by the longspears from below or beside the supports where reach permits. Do not assume enemies attack through solid bridge decking; use their actual lines of attack and positions.
- Waterline: Mossy rocks, fallen trunks, and submerged supports provide cover and terrain choices. The River Devils favor the water and will try to isolate anyone who steps into it.
- Avoid or distract: A quiet approach along the far bank, waiting until the patrol shifts, or diverting guardians away from the intake can create an opening. A fight is possible but not required to complete the objective.
- Difficulty: All five River Devils total 100 XP for five level-3 PCs (moderate), or 150 XP for five level-2 PCs (severe). Do not force the entire group into combat if the players find a plausible way around them.
Primary Objective — Deliver the Antidote
one prepared Watercourse Neutralizer dose must contact the infected living-root intake at the blackened bank. Pouring it into the middle of the moving creek will dilute and wash it away without treating the blight. Nature DC 18 identifies the polluted intake, though careful examination of the black film and golden threads can also reveal its position.
Without pressure: If the intake is accessible and the area secure, proper placement takes 10 minutes with no check. Under pressure: use the attached Neutralizer Placement — Silverrun Crossing challenge; Nature or Crafting DC 18 seats the portion in about 2 minutes. A failure delays placement or requires adjustment; it does not automatically consume the dose. The party need not defeat all five River Devils, but must secure enough access to the root intake for the neutralizer to take effect.
The antidote sinks into the infected root channel. Fine golden threads flare, then gutter out one by one. A black skin peels away from the rocks and breaks apart in the current. The water's strange sweetness fades, leaving only the familiar scent of wet stone and cedar.
Resolution and Consequences
Successful treatment interrupts this western feeder channel and clears the oily sheen locally. It is field containment, not the destruction of the central Stage 3 node. The River Devils are not automatically killed or cured by neutralizing the intake; they may become disoriented and linger, flee downstream, or continue defending their remembered source until they recover. Track whether they remain at the crossing and whether the party secured the bridge.
Report the blightwater's addictive effect, the five amphibious guardians, the status of the treated intake, and whether Silverrun Crossing is passable. If the western feeder is neutralized, the Cedar Court gains a safer route toward the interior; if left untreated, the contaminated water and its territorial defenders remain a danger.
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.
