The air, thick with the scent of damp earth and ancient stone, suddenly shifted. A fresh, warm fragrance, like a summer meadow, wafted down the spiral staircases, pulling the adventurers onward. One moment, they were descending into the unknown depths beneath the city of stone; the next, the stairs opened into a breathtaking, impossible vista.
Before them lay a subterranean valley, bathed in a soft, ethereal glow. Verdant greenery carpeted the floor, stretching between colossal, pyramidal pillars that soared 150 meters high, their apexes supporting the very rock ceiling of this hidden world. Grimnir, the grizzled dwarf, felt a shiver of awe despite himself. They had emerged at the top of one such gorgeously ornamented pillar, its spiral stairs continuing their descent to the valley floor. Along the right lip of this surreal chasm, a volcanic gulch burbled with molten lava, casting an orange hue on the surroundings. A wide, scorched furrow, thirty meters across, scarred the valley from the gulch to a steaming precipice. And then, the impossible: a large fireball, like a miniature sun, slowly rolled along the furrow, its passage leaving a trail of smoldering earth. This was the Sun Cave, a place of impossible beauty and perilous wonder.
Lucia, the group’s quick-witted druid, wasted no time. Her eyes scanned the landscape, her mind already calculating paths and possibilities. “This way,” she declared, pointing towards the descending stairs on their pillar, “We need to get down there, quickly.”
The descent proved as challenging as the lakes and muddy ditch had been long. The smooth, polished stone of the pyramid-like structures offered little purchase for the makeshift sleds they had fashioned.
“Pay attention!” Grimnir barked, his voice echoing in the vast space, as he expertly guided his sled down a perilous curve, Kristov, the peddler with a knack for sleighs, muttering instructions from the front.
“No, Sturmberg, sit on that side! You’re too heavy, you’ll make us crash!” Kristov, used to the open plains and swift sleighs, found the tight turns and sheer drops frustrating, but his skill was undeniable. Only he and Grimnir managed to navigate the treacherous slopes with any semblance of control. The others, less practiced, tumbled and slid, barely avoiding disaster.

Once on the valley floor, the air grew humid and thick with the scent of exotic flora. “Follow me,” Lucia commanded, her bushcraft instincts taking over as she plunged into the dense jungle that thrived in the subterranean warmth. Zarah, the wolfkin, usually stoic, let out a soft huff of disapproval at the sudden, chaotic plunge.
It wasn’t long before Zarah’s keen senses picked up on something. Her nose twitched, and her ears swiveled. “Lizard folk,” she whispered, her voice low and urgent. “Dwellings nearby, and… a fight.” Grimnir, ever cautious, unsheathed his daggers, their polished blades glinting in the dim light.
Through a break in the foliage, they saw them: a skirmish between the reptilian inhabitants of the valley. “I don’t want to get involved in that,” Grimnir stated, his hand still on his daggers, but his eyes scanning for an escape route.
Kristov, however, had an idea, his eyes fixed on the scorched furrow ahead. “The tin rope ladders!” he exclaimed. “We can use them to make slides and ramps, get the sleds and donkeys across the ditch!”
Lucia quickly ran the numbers in her head, factoring in the fireball’s slow but inexorable return. “We have, at most, two hours to make it across that ditch before the fireball reaches us again.” The decision was unanimous: they would go now, not wait.
Lupendus, the group’s resident master of dwarven alchemy, applied his diffident touch to the tin ladders. With a soft hum of magic, the flexible metal stiffened, becoming as rigid as steel, ready to bear the weight of their crossing.

The plan was set. They tied two ropes together, and Sturmberg, the burly warrior, carefully lowered Kristov into the ditch first. The peddler, nimble despite the awkward descent, landed safely on the other side.
Next was Lucia, riding a sled with Rudy, the donkey, to keep him calm. It was a perilous ride. Rudy, agitated by the descent, thrashed against her, and Lucia struggled to maintain control. In a heart-stopping moment, the donkey lost his footing, and he, Lucia, and the sled tumbled violently into the crevasse. Kristov, with his keen eyes, managed to dodge out of the way just in time. The crash was worsened by Grimnir’s nervous injury, a tremor in his hand that had caused a momentary lapse in the rope’s tension.
Lucia, battered and bruised, somehow managed to reach the handbrake, slowing their descent just enough to prevent a complete catastrophe, but she and Rudy were both injured, groaning softly.
Zarah peered over the edge, her voice surprisingly light. “Are you guys okay?”
“And we’re only halfway there!” Kristov called back with a laugh, his usual jovial nature undimmed by the near-disaster.
Despite her own pain, Lucia focused. Her hands glowed with faint magic as she laid them on Grimnir, healing some of his injuries. “We’ll need you healthy for the next time we get attacked,” she murmured, a grim determination in her eyes.
Zarah went next, struggling a bit more than expected, but still making it down safely, a chagrined expression on her face. Sturmberg followed, his sled descent smooth and controlled. He led the way to the other side, then, with a grunt, lifted Kristov up to the opposite bank. Zarah, even with the rope, struggled again, but with Kristov’s help, she and Sturmberg managed to haul the sled, Lucia, and Rudy up from the crevasse.
Grimnir, the last, ascended with difficulty, his recent injury making the climb arduous. The entire party strained, their muscles burning, to pull the final sled up and out of the ditch. They had made it, just barely.

Quietly, the group pushed through the remaining jungle, their movements hushed, mindful of any unseen eyes. Their goal was the next ridge, at the far end of the valley, and the promise of escape from the Sun Cave’s dangers.
They reached it, a sheer rock face, and at its base, a closed stone gate. In its center, a hole shaped like a metal heart. Beside the gate, a statue of a kindly dwarf stretched its hands towards them. Above the gate, an inscription read:
“Let hands unite, May warmth of love open the heart’s door.”
As dusk settled over the subterranean valley, Kristov and Sturmberg began to set up camp, while Lucia, ever practical, led the party to the doorway, examining the strange, heart-shaped lock.
The night passed uneventfully, a rare moment of peace in their perilous journey. As morning light began to filter into the cave, Grimnir, ever curious, took one of the hands from the dwarf statue. It felt cold, inert. He handed it to Lucia. After a moment of investigation, her eyes widened. “It reacts to heat,” she announced, a spark of understanding in her voice. “I think it’s some kind of key.”
“This must work on the door,” she concluded, “Nothing else makes sense.”
Kristov put his tinkering mind to the task and tried his best to craft the metal hand into a key, twisting and bending it, but to no avail. It remained a hand.
“Maybe it needs more than just a touch of warmth,” Sturmberg mused, and without hesitation, he tossed the metal hand into their dying campfire.
The reaction was immediate and dramatic. The metal hand glowed, then began to writhe, its fingers twisting and contorting until, with a final click, they locked into the precise shape of a key. They tried it on the door. It fit. With a soft rumble, the stone gate swung inward.

A rich, earthy, but not unpleasant, smell greeted them. Before them stretched an oblong cave, disappearing into the distant gloom. Giant mushrooms, some taller than a man, grew like a fantastical forest on the cave floor.
They ventured into the mushroom cave. Lucia, always the experimenter, plucked a small mushroom and took a bite. It tasted like absolutely nothing. She spat it out, and the rest of the party looked on with disgusted expressions. “It wasn’t very tasty,” she clarified, noticing their glances, “but it wasn’t bad.” Kristov wondered if they should take some supplies, despite the bland flavor.
Using his talent for poisons, Kristov carefully examined the various fungi, identifying which were dangerous and which were benign.
The party attempted to make their way through the mushroom forest stealthily, but the soft, spongy ground and the sheer size of the fungi made it impossible. Their footsteps echoed, and the rustling of their gear seemed amplified in the quiet cave.
Zarah, however, picked up on something else. Her ears twitched, and a low growl rumbled in her chest. “We’re being hunted,” she warned, her voice tight. “I’m not sure what it is, but it’s close.”
They quickly set up defenses, using the sleds as a makeshift barricade, positioning them in front of some of the larger mushrooms, creating a narrow funnel. Grimnir melted into the deeper shadows, daggers ready. Kristov, meanwhile, set a trap, rigging one of the sled’s brakes to snap shut if disturbed.
The attack came swiftly, silently. Three monstrous spiders, their eyes gleaming with malevolent intelligence, lunged from the darkness, their fangs dripping with venom. It moved with terrifying speed.
Sturmberg rushed out to face one of the beasts, forcing it to slow its advance. The rest of the party dodged the incoming attacks from the other two spiders, slashing back with knives and swords as they could. Zarah attempted to get to a better vantage point to start sniping with her bow, but the barricades slowed her progress as well.

Letting one of the spiders get in close, Kristov sprung the spike trap on it, piercing the spider’s hide and ensnaring it. The other adventurers took the fight to the remaining free spiders and slowly hacked at the creatures’ limbs. Eventually, two of the spiders sensed their ends were near and made desperate attempts to escape. The party allowed those to leave, turning their attention to the trapped spider.
Instinctual fear took over the monster’s mind as it tore itself free from the snare. It lashed out with limb and fang against all the adventurers. While most of the warriors were able to dodge or shrug off the attacks, they looked on with horror as one of the sharp legs of the giant spider pierced through Kristov’s chest, killing him instantly.
The spider let the peddler’s body slide off its leg as it turned to disappear back into the mushroom forest. Moving as fast as it could, the beast tried to dodge away from the encroaching dwarven warrior and human druid to no avail.
Lucia screamed, a guttural cry of pure rage, and plunged her sword into its chitinous body as it tried to escape. Sturmberg, witnessing Kristov’s death, let out a primal roar, a berserker rage taking hold. He charged, his axe a blur, utterly destroying the monstrous spider, hacking it to pieces until nothing but a twitching, pulpy mess remained.
The mushroom cave, once a place of strange beauty, was now stained with blood and grief. Kristov, the jovial peddler, was gone. The remaining party members stood in stunned silence, the reality of their loss settling heavily upon them. The journey continued, but it would never be the same.
