Introduction

Adventure Background

Before the gods shaped the first dawn, before the stars were kindled and the planes of existence spun into being, there was only the Void. And within the Void, there was Zelgor - the First Shadow, the darkness between the stars, the silence before the first word was spoken. He is not a god, for gods are things that were created. Zelgor simply is.

Three creations have risen and fallen before Aedelore. Three complete realities, each with their own peoples, their own heroes, their own songs - born from divine will and unmade by Zelgor's hunger. Aedelore is the Fourth Dream, the gods' last act of creation. The divine well runs dry. If Zelgor consumes this world as he consumed the others, the cycle ends. Only the Void remains.

Thousands of years ago, Zelgor's influence found a crack in Aedelore's defenses. In a great elven city - once known as one of the jewels of Aedelore, a breathtaking metropolis where the shimmering waters of the Iridescent River flowed past towering spires and elven architecture, blessed by the divine light of the dragon goddess, Tohu - the beloved king Malcath ruled with wisdom and grace. But Zelgor is patient. Through a Void creature named Zarathen - a being of whispers and false promises - Malcath was offered what no mortal should possess: divinity itself. The price was everything. Malcath sacrificed his own people, his own city, and his own soul. The gleaming spires sank beneath the earth, and what remains is now known only as the Sunken City - a tomb of thousands, sealed away from the world above.

But Malcath's soul was not wholly consumed. The goddess Tohu intervened with the last of her available strength, casting Malcath's corrupted essence into the Void between worlds. And the archmage Auren Vale, founder of the Arcane Creed, designed a network of nine portal anchors spread across the continent - each one holding a thread of Malcath's remaining humanity. Nine threads. Nine anchors. A web of mercy stretched across the world, built not to imprison the fallen king, but to preserve what was still worth saving.

Now, centuries later, the anchors are failing. Three portals have already collapsed. A cult calling themselves "The King's Voice" works to break the rest, believing that Malcath's return will bring salvation. They are wrong about who they truly serve. The hand that moves them reaches from far deeper than any king's grave - it reaches from the Void itself, from Zarathen, who hungers to finish what he started.

The threshold is simple and terrible: if one more portal breaks, Malcath awakens - not as a king, but as a weapon of the Void. The Fourth Dream ends.

The dreams come every night now. A city of white stone sinking into darkness. A voice calling from beneath the earth - not words exactly, but a feeling, like a hand pressed against the inside of your skull. And always the same image at the end: figures standing at the edge of an abyss, holding torches against a wind that wants to extinguish everything.

The player characters are drawn together not by chance but by fate - or something older than fate. Each has experienced the dreams. Each carries a fragment of a prophecy they do not yet understand. And one among them carries something more: a connection to the portal network that even they do not know about. A seed planted centuries ago by Auren Vale herself. The Tenth Filter - a living key designed to restore what was broken.

Adventure Synopsis

The Heir of Shadows unfolds across six chapters. Each chapter escalates the stakes and deepens the mystery of Zelgor, Malcath, and the fate of the Fourth Dream.

Chapter 1: The Fragmented Ring

The adventure begins in the trade town of Avenstoff, where rumors of an artifact from the Sunken City draw the party together. A mysterious ring, a shadowy figure named Draven Holt, and an enigmatic elven archivist named Eryn Duskwhisper lead the party to the Badger Caves - the first of nine portal anchors - where they must renew a failing seal before it breaks entirely. The party learns that this is only the beginning: a cult is actively working to destroy the remaining portals, and the clock is already ticking.

Chapter 2: Amber and Stone

The party travels to Amber's Call, an ancient dwarven ruin containing a sealed library and the last functioning portal map. There they discover the full scope of the crisis: nine portals, three already collapsed, and a cult racing to break the rest. At Serexa Fortress, the party gains powerful allies - the anti-Void specialist Archon Thelian and the enigmatic halfling mystic Mother Bryn - before marching into the corrupted Brightwood to confront a cult encampment and seal the second portal through an act of divine intervention.

Chapter 3: Roots and Shadow

The party seals the Shadow Lake portal - the most dangerous of all, lying directly above the Sunken City - before learning that the Alfwyld Forest, homeland of the halflings, has been invaded by cult forces. A desperate march, a battle at the forest's sacred heart, and the awakening of the Great Tree test the party's resolve and forge new alliances.

Chapter 4: The Purification

Returning to Serexa Pass, the party confronts Bhorin Ambervane - an ancient dwarf king who has channeled Void energy for centuries, believing he was protecting Malcath's humanity. The truth is more complex than anyone imagined. In a dramatic ritual, all six sealed portals are purified simultaneously, transforming the anchors from failing seals into living connections. One party member is permanently bound to the network - and begins to change.

Chapter 5: The Weaver's Web

Intelligence reveals that the true mastermind - known only as the Weaver - has been operating from the elven capital of Lorenzia all along. The party infiltrates the city, navigates political intrigue among the Star Council, and breaks into the sealed eastern archives of the Arcane Creed. There, they discover the devastating truth: one of them was designed by Auren Vale herself - the Tenth Filter, a living bridge capable of restoring Malcath's humanity. The Weaver is not an enemy. He has been waiting for this moment for nearly three centuries.

Chapter 6: The Recall

With allies gathered from across Aedelore - dwarven armies, elven paladins, and the remnants of the Arcane Creed - the party marches on the Sunken City. While the army holds the shore against Void creatures, the party descends into the drowned ruins to perform the Recall - a ritual to restore Malcath's eight remaining threads of humanity and pull him back from the Void. The chapter culminates in a confrontation with Zarathen himself, a moment of terrible sacrifice, and a choice that will determine whether Aedelore's story continues. The arc closes with the founding of Valbron - a new city built on the bones of the old, a symbol of hope where there was only darkness. But the story does not end here.

Running This Adventure

The Chosen One

One player character is secretly the Tenth Filter - a living component of Auren Vale's portal network, designed centuries ago to be the key to Malcath's restoration. This is the adventure's central mystery and should be revealed gradually.

Tone

This is a dark fantasy mystery with cosmic horror undertones and moments of genuine warmth. The world of Aedelore is beautiful - its cities magnificent, its people vibrant, its landscapes breathtaking. But beneath that beauty lies something ancient and incomprehensible that wants to unmake everything. The best sessions balance wonder with creeping dread. Let the players love the world before you show them what threatens it.

Player Agency

The adventure has a strong narrative spine - the party will ultimately face the Sunken City and perform the Recall - but the path there should feel like the players' own. Many encounters offer multiple solutions: combat, diplomacy, stealth, or creative problem-solving. NPCs have their own motivations and can be persuaded, deceived, or befriended. When players devise solutions not covered by the text, say yes whenever possible.

Scaling

The adventure is designed for 3–5 players. All combat encounters include scaling notes for smaller or larger parties. Key NPCs can be added or removed from the party's traveling companions to fill gaps - if the party lacks a healer, Naia or Mother Bryn can fill that role; if they lack muscle, Draven or the battle mages can join.

Pacing

Each chapter is designed for 1–2 sessions of play (3–5 hours each). Chapters 2 and 5 are the longest and may require two sessions. Chapter 6 can be split naturally at the Recall itself - ending one session with the descent into the Sunken City and beginning the next with the ritual.

Key Themes

Mercy Over Vengeance

The portal network was not built to imprison Malcath - it was built to preserve his humanity. The adventure challenges the assumption that fallen beings must be destroyed. Malcath chose corruption, yes, but the question is whether he deserves the chance to choose differently. The party's answer to this question shapes the entire campaign.

Identity and Purpose

The Chosen One was literally designed for a purpose they never asked for. Their entire existence was orchestrated by someone who died centuries ago. How do you find meaning in a life that was planned before you were born? The other party members face their own version of this question: are they here by choice, or by fate? Does it matter?

The Cost of Truth

Every chapter peels back another layer of a truth that grows more devastating as it deepens. The world is the last in a line of failed creations. The portals are not prisons but lifelines. The cult leader may not be an enemy. The Chosen One may not be entirely human. Characters must decide whether to bear this knowledge, share it, or try to forget it.

Corruption and Redemption

Power offered freely always has a price. Malcath's story is the central cautionary tale - a good king who believed he could control the Void's power. But the adventure also asks: what happens after the fall? Is redemption possible for someone who destroyed an entire civilization? Several NPCs - Draven, Bhorin, even Malcath himself - embody different answers to this question.

The Nine Portals

The portal network spans the continent. Each portal is anchored to one or more of the Eleven Seals - fundamental principles of reality that hold the barrier between existence and Void. Understanding this network is essential for running the adventure.

Recurring NPCs

Adventure Hooks

The adventure begins with all player characters converging on the trade town of Avenstoff. Work with your players during Session 0 to establish why their characters are there. Below are suggested hooks for different character types:

• The Scholar or Mage. Rumors of an artifact from the Sunken City have reached academic circles. You came to verify whether the item is genuine - and if so, what it means that objects from a sealed tomb are surfacing after centuries of silence.
• The Soldier or Guard. Strange reports from the outskirts: travelers gone missing, cult markings on trees, and a general sense of unease among the garrison. You were sent to investigate - or you came on your own, following a soldier's instinct that something is very wrong.
• The Rogue or Drifter. A bustling trade town full of merchants, travelers, and nervous guards means opportunity. You came for the coin. But the dreams that have plagued you for weeks grow louder here, and the feeling that you are exactly where you are supposed to be is impossible to shake.
• The Cleric or Devout. The dreams started weeks ago - visions of white stone sinking into darkness, a voice calling from below. Your god has not explained, but the pull toward Avenstoff is undeniable. You are here because something sacred requires your presence.
• The Ranger or Druid. The land is sick. The Dunmer Forest near Avenstoff is dying from something that is not natural. Animals flee east. Water tastes wrong. You followed the signs here, and what you have found suggests the corruption runs far deeper than poisoned soil.

The Eleven Seals

The portal network is anchored by principles called the Eleven Seals - fundamental truths of reality. Understanding them is not required to play, but enriches the experience. Mother Bryn teaches the party about them in Chapter 2, and they become mechanically relevant during portal sealing rituals.

What You Need

• The Aedelore core rules (available here)
