The entrance to the Chamber loomed before them, an ancient, jagged crack carved into the cliff side by centuries of weathering and magic. The final clue had led them here, to a hidden doorway concealed by layers of enchantments that they had painstakingly unraveled. The air was thick with anticipation and the faint tang of ozone, as though the very earth knew they were about to cross a threshold long left undisturbed.

Carlos stood silently beside Lando, his expression unreadable. The moonlit night cast silvery highlights across the landscape, but the darkness seemed to pool heavier around the entrance. Lando glanced at him nervously.

"This is it," he said, his voice barely above a whisper.

Carlos gave a short nod, gripping his wand tightly. Lando took a deep breath and stepped forward, pressing his hand against the rune-inscribed stone that marked the threshold. The runes glowed faintly, their icy blue light spreading like veins through the rock. With a low groan, the stone parted, revealing a narrow passage that descended into darkness.

As they stepped through, a sudden wave of energy washed over them. The wands in their hands fizzled uselessly, and a strange stillness settled over the space.

"Our magic- " Lando started, looking at his wand in alarm.

"It's gone," Carlos finished, his voice tense.

It wasn't just their magic. Carlos felt the familiar shimmer of his Glamour fade from his skin. He braced himself for Lando's reaction, his scars now fully visible in the faint glow of the runes lining the walls. But Lando seemed too preoccupied with their surroundings to notice the change.

The corridor twisted and turned, the air growing colder with every step. The walls were carved from black stone, etched with sigils that pulsed faintly, as if alive. Ahead, the passage opened into a vast cavern.

The room was breathtaking. Massive pillars stretched from floor to ceiling, their surfaces inlaid with intricate carvings of stars, constellations, and ancient beasts. The floor was a mosaic of shimmering tiles that reflected the dim light of enchanted flames flickering in sconces along the walls. At the center of the room stood a raised dais, its surface inscribed with the same runes that had guided them here.

"It's beautiful," Lando breathed, stepping forward to inspect the carvings. "It's like a map of the stars..."

Carlos didn't respond, his attention fixed on the dais. There was a strange pull, a sense of foreboding that made his stomach churn.

Before he could warn Lando, the chamber came alive. The runes flared, casting eerie shadows across the walls, and a deep rumble echoed through the space. Dark tendrils of energy erupted from the floor, coalescing into shadowy figures that advanced toward them.

"Look out!" Carlos shouted, shoving him aside as one of the figures lashed out with a jagged, shadowy blade.

Without their wands, they were defenseless. Carlos grabbed a loose shard of stone from the ground and swung it at the nearest figure, the makeshift weapon passing harmlessly through its incorporeal form.

"They're not solid!" Lando yelled, dodging another attack.

Carlos' mind raced. These weren't ordinary enemies; they were manifestations of dark magic, immune to physical attacks. "Get to the platform!" he shouted. "It might be the key!"

Lando nodded, darting toward the platform as the figures closed in. Carlos followed, narrowly avoiding another attack that left a searing gash across his sleeve.

As they reached the dais, the shadows hesitated, circling them like predators waiting for the right moment to strike. Lando frantically examined the runes, his fingers tracing the patterns. "There's... there's a sequence here, but I don't-"

"Just try something!" Carlos snapped, gripping the edge of the dais as the shadows pressed closer.

Lando muttered under his breath, pressing a series of runes in rapid succession. For a moment, nothing happened. Then, with a blinding flash of light, the shadows dissolved into mist.

The silence that followed was deafening.

Carlos and Lando stood frozen, their breaths coming in ragged gasps. Slowly, the oppressive weight lifted, and the faint hum of magic returned to the air.

"Our magic..." Lando whispered, lifting his wand. A faint spark danced at the tip.

But Carlos' glamour remained absent, his scars stark against his skin. He turned away quickly, avoiding L's gaze.

"What was that?" Lando asked, his voice shaky.

"A warning," Carlos said grimly. "And probably just the beginning."

Lando hesitated, his eyes lingering on Carlos' face. "You're not-"

"Not now," Carlos interrupted, his tone brooking no argument. "We need to keep moving before something worse shows up."

Reluctantly, Lando nodded, and they stepped toward the archway that had appeared on the far side of the chamber. Beyond it lay another corridor, dimly lit and lined with strange, twisting carvings that seemed to shift as they passed.

Despite the return of their magic, an uneasy silence hung between them. Lando stole glances at Carlos, questions burning in his eyes, but he held his tongue. For now.

The Chamber of Shadows was far from done with them, and whatever trials lay ahead, they would need to face them together.

The air in the chamber was heavy, each breath a struggle as though the darkness itself weighed on their lungs. Carlos and Lando pressed forward, their footsteps echoing faintly against stone walls that seemed to shimmer and ripple like liquid.

"This place," Lando muttered, running his fingers along the smooth wall, "It's alive, isn't it? Like it's watching us."

Carlos didn't reply. His shoulders were tense, his eyes darting to every shadow. Something felt off- dangerous, in a way that even the enchanted lake and cursed ice hadn't been.

They stepped into a circular room. Runes glowed faintly on the floor, forming a pattern too intricate to decipher at a glance. The walls, polished to a mirror-like finish, reflected their every move.

"I don't like this," Lando said, his voice low.

"Stay close," Carlos murmured, gripping his wand tightly.

Then the whispers began. Faint at first, like the rustling of distant leaves, but they grew louder with each step toward the center of the room.

"Do you hear that?" Lando asked, glancing nervously at Carlos.

"They're... voices," he replied, his voice strained.

The whispers coalesced into fragmented words, phrases that echoed with an unsettling clarity. Lando's name drifted through the air, spoken in tones both tender and accusatory. Then came fragments of his past- his father's stern reprimands, his mother's soft encouragements, the laughter of friends mingling with the sting of failures he had never confessed.

"No," Lando whispered, taking a step back. "How- how does it know these things?"

"It's pulling from us," Carlos said, his voice sharper now. His heart was pounding; the room wasn't just drawing from them- it was dissecting them.

The shimmering walls flickered, the reflections within coming to life. Lando's childhood played out in fractured images: him learning to fly, winning his first match, but then faltering on a broomstick, tears streaming down his face. The scenes shifted to moments of loneliness, nights spent staring at the stars, wondering if he'd ever truly belong.

"Stop it," Lando choked out, turning away.

But the reflections didn't stop. They shifted to Carlos, though not the version of himself he presented to the world. They showed scars- long, jagged lines crissc-rossing his arms and chest. Then his body contorted, his features twisted with pain, black veins creeping across his skin like spilled ink.

Lando gasped. "... What is that? What am I seeing?"

"It's nothing!" Carlos yelled, stepping in front of the reflections as though to block Lando's view.

"Nothing? I- what?"

The runes on the floor pulsed suddenly, and the whispers crescendoed into a cacophony. Carlos' own voice echoed through the chamber, snarling and guttural, words he didn't remember speaking but that dripped with anguish.

"Get out of my head, Confringo!" Carlos roared, firing the spell at the shimmering walls. The light from his wand refracted off the surfaces, but the images persisted.

"Stop!" Lando grabbed his arm. "This isn't helping!"

Realising the futility, Carlos lowered his wand, his breaths ragged. "We need to leave. Now."

He pulled Lando toward the nearest archway, the reflections fading as they stumbled out of the room. They didn't stop until they were several corridors away, the oppressive whispers replaced by silence.

Lando turned to Carlos, his face pale and drawn. "What was that? Those- those images- what were they?"

"Just illusions," Carlos said flatly, not meeting his gaze.

"Don't lie to me," Lando demanded, his voice trembling with equal parts anger and concern. "I saw-"

"Stop!" Carlos snapped, cutting him off. His voice echoed in the empty hall, sharp and final.

Lando flinched, taken aback by the vehemence in Carlos' tone. Without another word, Carlos stalked ahead, leaving Lando standing alone in the dimly lit corridor, his thoughts swirling.

Later that night, Lando sat in an armchair by the Gryffindor common room fire, staring into the flickering flames. The warmth did little to ease the chill that had settled in his chest. They had returned to Hogwarts, neither had the physical or emotional energy to proceed with the Chamber for the time being.

He replayed the events in the reflective room over and over. The voices, the images- they had dredged up things he had buried long ago. Insecurity, loneliness, the nagging fear that he wasn't enough.

But those were things he could accept about himself. What he couldn't understand- what he couldn't shake- was what he had seen of Carlos.

The scars, the black veins- they didn't make sense. They still didn't make sense. They didn't belong to the Carlos he thought he had known for the last seven years.

What is it that he's hiding?, Lando thought, his brow furrowing. It's something big, whatever.

Carlos' outburst replayed in his mind, the way his voice had cracked with anger and something else- fear, maybe?

Why won't he trust me?

Lando clenched his fists, frustration bubbling up. "I've been there for him," he muttered under his breath. "I've stood by him through everything. Why can't he just-"

He sighed, leaning back against the chair. Deep down, he knew the answer. Carlos had always been guarded, always kept a part of himself locked away. Lando had accepted that as part of who he was, but now... now it felt personal.

The Chamber is testing us, Lando thought, staring into the fire. It's exposing us, breaking us down. But why? What does it want us to see?

He thought back to Carlos' face in the corridor, the way his jaw had been set, his eyes burning with something Lando couldn't place. Pain? Guilt?

I'll find out, Lando resolved silently. Whatever it is, I'll find out. And when I do, I'll prove to him that he didn't need to hide it from me, that I'll be there for him.

But as the fire crackled softly, Lando couldn't shake the gnawing worry in his chest. Whatever he was hiding, it felt bigger than both of them- something that could shatter their friendship if it came to light.
