In “The Plane Walker,” a party of 3-5 characters (level 5) investigates bizarre temporal disturbances plaguing the remote village of Wyrm’s Hollow — livestock aging overnight, crops withering in hours, shadows moving on their own. The source is Aerion Tyvalis, a once-legendary knight who died defending innocents and whose soul was corrupted by a malevolent entity from the Negative Plane. Transformed into a Plane Walker and blinded by regret, Aerion has seized a Ruined Sanctum and is using a Temporal Gate to reshape his own past — unaware or uncaring that his actions risk a catastrophic planar breach. The party must investigate the village, battle through the Sanctum’s warped corridors, and ultimately chase Aerion into his own fractal demi-plane for a final confrontation where redemption and destruction both lie within reach. The adventure is divided into three parts.
Part 1: Call to Action
The party arrives in Wyrm’s Hollow, where a desperate mayor greets them with relief and a negotiable reward. An optional opening encounter with villagers caught in temporal ripples sets the unsettling tone and establishes the non-lethal stakes. Three investigation threads reward a thorough party — a haunted well that yields a vision at midnight, an eccentric elven sage who can name the source of the anomalies, and an abandoned temple that links the blight to a fallen knightly order. With their leads gathered, the party sets out for the fog-shrouded forest.
Part 2: Temporal Rift
The mist-laden path to the Sanctum is haunted by warped time itself — flickering wolves, temporal sinkholes, spectral echoes of Aerion, a grove where all motion is frozen, and landmarks that shift and loop the unwary back on themselves. The Ruined Sanctum beyond, once dedicated to Helm, is so saturated with warped temporal energy that simply lingering takes a toll. Its chambers each hold their own threat and their own fragment of Aerion’s story — mirror-born duplicates, spectral archivists guarding his chronicles, vaults that tempt the greedy, a chapel that can restore a weary party, and a guardian who may grant safe passage to those who can reason with it. At the Temporal Gate, defended by corrupted knights amid arcane surges, the party makes its first major choice: stabilize the Gate and pursue Aerion, collapse it to stop the immediate breach, or refuse to cross at all — each path carrying its own consequences.
Part 3: Final Confrontation
Crossing into Aerion’s fractal demi-plane, the party traverses shifting landscapes of marble and ancient cobblestone beneath a sky churning with battles past and future, where gravity itself cannot be trusted. The Temporal Fortress reflects Aerion’s fractured psyche chamber by chamber — a hall where the statues of his fallen comrades come to life, a battlefield of illusory warfare where the right words called out mid-combat may reach the knight inside the monster, and a chamber of echoes whose visions can be turned against him. In the Negative Nexus, Aerion Tyvalis waits before a churning maelstrom of black and silver, sustained by the entity that corrupted him. Three climactic paths decide the outcome: redemption, convincing Aerion he was manipulated so that he seals the rift himself at the ultimate cost; combat victory, collapsing the fortress in a desperate escape; or catastrophe, in which the rift merges the Negative Plane with reality and a campaign-scale invasion looms. The ending reshapes the world — a redeemed Aerion becomes a legend of hope and time stabilizes across Wyrm’s Hollow; a defeated Aerion ends the threat but leaves residual distortions for future adventures; an opened rift darkens the sky and sets the stage for a larger planar campaign.
