Expedition to the Heart of Earin

The four adventurers

The expedition took place during the Civil War of the Gods. Its members were Marlo Quince, the wizard Erynd Solen, the cleric Vorstag, and an infernal adventurer remembered in surviving accounts only as the Devil.

Marlo had brought them together with the promise that the object called the Heart of Earin could grant their deepest wishes. Erynd hoped it might cure the inverted lycanthropy that made a wolf his natural form. Vorstag descended as a proven servant of Merynn, having hunted monsters and devils in these caverns before with her full divine support. The Devil travelled beside the cleric for reasons the surviving record does not preserve.

Marlo's deeper interest in Erynd was his silver suppressor bracelet. It forced Erynd's curse back upon itself through magical resonance, sustaining his human transformation at the cost of continuous pain. Marlo believed the same contradiction could be used to rouse the dormant Heart.

The canyon of forgetting

The four awoke at the bottom of a vast canyon with no memory of who they were or why they had descended. Marlo, Erynd and Vorstag lay upon a narrow ridge. The Devil was far below, almost completely hidden within a field of luminous nhalis, or amnesia grass.

At such depth the grass was exceptionally potent. Every movement awakened waves of cold light and released clouds of spores that stripped memory away in descending layers: first purpose, then immediate action, identity, language and finally the learned commands of the body. Left within the field, a victim could forget how to draw breath.

The Devil retained just enough instinct to force himself towards the cliff. The three figures above, themselves reduced to fragments of personality and half-remembered abilities, lowered what they could and dragged him out of the grass.

The gnome in the mushroom tree

A small, peculiar gnome appeared above the canyon, complained that the bridge was always breaking and threw down a rope. He led the strangers through the caverns while casually gathering fungi, roots and luminous mosses.

The gnome lived with his wife inside a gigantic tree-like mushroom whose ancient stalk had hardened like timber. Together they brewed a restorative potion. Names returned first, followed by loyalties and finally the purpose of the expedition.

The gnome directed them towards the nearest settlement and offered no explanation of himself. Much later evidence identifies him as Fizz, encountered in the far later years of his life. The travellers never realised whom they had met.

Stillreach

Stillreach stood alone in the Lower Underdark, far from any dependable road, mine or kingdom. It was a sanctuary for those who became lost below and sheltered many peoples, though most inhabitants were Nethren, a deep-cavern people formerly enslaved by the Drow of a nearby fortress.

A rough statue dominated the village square: an enormous surface warrior with an axe and a broken chain. A Nethren girl explained that he had freed her people before she was born. The warrior was Gorran Chainbreaker, whose descent roughly thirty years earlier had allowed Stillreach to exist.

The silence of Merynn

In Stillreach, Vorstag discovered that his divine power had simply ceased. At first he blamed the depth, but he had hunted through the Underdark before with Merynn's support undiminished. A religious elder offered the explanation he feared: when a god dies, the power granted to that god's clerics can vanish with them.

Vorstag accepted that Merynn might be dead. He nevertheless carried her final feather and continued towards the Heart without knowing whether any prayer could still reach her.

The Drow seizure

An invisible force began moving through the crowds of Stillreach. An elite Drow unit had entered the sanctuary to seize the surface travellers. The attempted arrest became a battle across the village until the Drow commander emerged, ordered every combatant to stop and had the four taken to the nearby fortress.

Within its lower cells the party found a withered, eccentric prisoner who babbled about darkness in the temple beyond the walls. He told them that the Heart had descended into the Underdark in a remote age. Temples had been raised around it, wars fought for it and entire peoples destroyed in the attempt to possess it.

A great beholder eventually killed almost everyone in the old fortress. A surviving circle of sorcerers could not destroy it, so they bound the creature to the temple as the Heart's unwilling guardian. It had remained there for thousands of years.

The false wall

Near the temple, reality had ceased to behave properly. The beholder's dreaming presence distorted the surrounding region while the Heart exerted impossible effects of its own. Where the two influences overlapped, distance, stone and perception contradicted one another.

One corner of the prison wall proved to be a mirage. It gave way into a hidden passage beyond the fortress, opening onto an expanse of black sand and the ancient temple of the Lantern.

Merynn's final answer

The beholder awakened when the expedition entered the inner shrine. Its eyes filled the temple with intersecting rays while its regional distortions turned walls into openings, distances into traps and solid ground into illusion. By the time the guardian was wounded, the party had been bloodied almost beyond resistance.

Vorstag remembered Merynn's final words and raised the feather she had left him. Beneath the light of the Heart, Merynn returned—not restored to life, but present for one last instant to answer her cleric's divine intervention.

Vorstag became her champion. Light poured through him and around his great hammer. He brought it down upon the beholder in a burst of white fire and burned the creature to ash. The feather crumbled with it. Merynn vanished, and the last remnant of her left the world.

Awakening the Heart

The guardian's destruction did not awaken the Heart. It remained suspended within the shrine: radiant, unreachable and silent. Marlo then revealed the purpose for which he had truly recruited Erynd.

Erynd removed the silver bracelet. His human transformation broke immediately and the wolf emerged—not Erynd in another shape, but the uncontrollable creature his failed ritual had made his natural body. It attacked the nearest living thing it perceived. Vorstag and the Devil held it back while Marlo fought his way to the shrine with the bracelet.

Marlo fastened the device against the Heart. Its feedback forced the relic's immeasurable magic to answer itself. For one moment nothing happened. Then the Heart beat.

The pulse crossed the temple, the fortress and the innumerable layers of stone above. The Heart tore free and rose through the world as though the earth had become insubstantial. As the temple began to collapse, Marlo and Vorstag wrestled the bracelet back around the wolf's limb. Silver met the curse, the feedback closed once more and Erynd's human form returned before they fled.

The Devil's last bargain

The expedition summoned spectral horses to flee across the black sands, but the Heart's pulse had begun to unmake lesser magic. The steeds flickered with every shock passing through the temple. They could carry the party only while someone remained at the summoning mark and held them in the world.

The Devil chose to stay. He carved his true name into the mark and bound the spell to it. So long as his name endured, the horses would remain solid beneath the others. Marlo, Erynd and Vorstag rode while the Devil held the failing threshold behind them and fed his own existence into the spell.

When the temple collapsed, the mark—and the true name written within it—was destroyed. Devils normally returned to their native realm when killed elsewhere. This death was different: he had made his continued existence the price of the others' escape. He did not return.

The star above the battlefield

Marlo, Erynd and Vorstag reached the surface beneath a new star. The Heart hung in the sky, bright enough to be seen across the war-torn world.

The gods saw it too. Across the battlefield, the divine hosts lowered their weapons and knelt. They did not know what the light was, only that it carried a power older and greater than their own. They believed Earin had returned.

The expedition had not resurrected Earin, restored Merynn or granted the wishes Marlo promised. Four damaged travellers had entered a forgotten place, awakened something the gods themselves feared, and forced the Civil War to look upward. Only three came back.

Legacy

The expedition became one of the defining mortal interventions of the Civil War of the Gods. Later histories often reduced it to the rising of the Heart, overlooking the lost sanctuary, Gorran's rough stone likeness, Merynn's final answer and the unnamed Devil whose last bargain allowed anyone to carry the story home.

Marlo survived with the purpose of his descent fulfilled. Erynd returned wearing the bracelet that preserved his humanity but had not cured him. Vorstag emerged as Merynn's final champion and the witness to her complete departure. The Devil remained beneath the earth. His personal name was lost, but his choice was not.
