The passage beyond the stone wall felt like stepping into a different century. The air was heavy, smelling of ozone and the dry, metallic tang of ancient magic. As the dust settled, the four Gryffindors stood at the threshold of a corridor that seemed to stretch infinitely into the dark.
"Right," Albert said, breaking the silence. He didn't just walk in. Instead, he flicked his wand, and the debris from the broken griffin statue began to swirl. Wood from a nearby fallen branch joined the stone chips, knitting together into a large, solid wooden sphere about the size of a Muggle medicine ball.
Fred watched the ball thud onto the stone floor. "A bit overkill on the caution, don't you think? We've already killed the monsters and opened the door. How many more layers does this onion have?"
Albert didn't even look back. He was busy tapping the sphere with a series of diagnostic charms. "If you're feeling particularly brave and want to be our literal guinea pig, be my guest, Fred. Step out into the dark. I'm sure whatever traps are waiting for you will be very educational for the rest of us."
Fred's bravado vanished instantly. He took a half-step back, grumbling under his breath. "Alright, alright, point taken. I'm a fan of the ball. The ball is a great idea. Long live the ball."
George and Lee Jordan were huddled behind Albert, snickering at Fred's quick retreat. To hide his embarrassment, Fred cleared his throat and tried to look professional. "So, let's talk business. What's at the end of the rainbow? If it's just more stone fingers, I'm going to be very annoyed."
"Probably the Sword of Gryffindor," Albert said casually, giving the wooden ball a sharp nudge with his foot. It began to roll forward, its hollow echoes providing a rhythmic soundtrack to their tension.
"The sword?" Lee's eyes went wide. "The one from the stories? The one that only appears to a 'true Gryffindor' in a time of need?"
"It's a logical candidate," Albert explained. "Godric wasn't a man of subtle trinkets. He was a warrior. If he left a legacy behind, it's going to be something sharp and silver."
They didn't get more than twenty yards before the corridor changed. A thick, swirling mist began to seep from the walls, pooling on the floor until it reached waist-height. It wasn't normal fog; it glowed with a faint, sickly violet hue and seemed to hum with a low-frequency vibration.
Albert stopped the wooden ball at the edge of the mist. He let it roll in, then used a summoning charm to jerk it back. The wood was dry. No acid, no rot, no physical change.
"It looks... weirdly calm," George noted, his brow furrowed. "Usually, when things look this peaceful in a dungeon, it's because they're about to turn you inside out."
Albert turned to Fred, a small, slightly sinister smile playing on his lips. He flicked his wand again, and the rope that had been coiled in his belt lunged forward, tying itself firmly around Fred's waist in a complex harness.
"Oi! What's this then?" Fred yelped, trying to untie the knots.
"Promotion," Albert said, patting Fred on the shoulder with mock affection. "You've been promoted to Lead Scout. It's time to show that 'daring and nerve' the Sorting Hat was so fond of. Don't worry—if you start screaming or the rope goes slack, we'll haul you back like a prize trout."
Fred's face went through several shades of pale before settling on a resigned sort of gloom. "I hate you lot. Truly."
He took a deep breath, checked his wand, and stepped into the violet haze. The moment he vanished from sight, the rope went taut. Then, it went slack. Then, a muffled, strangled cry echoed through the mist.
"Pull him back! Now!" Albert commanded.
The three of them heaved on the rope. A second later, Fred came flying out of the fog, skidding across the stone floor on his backside. He looked like he'd just seen his own funeral. He was trembling, his eyes darting around as if the ceiling were about to collapse.
"What happened?" George asked, kneeling beside his twin. "Was it spiders? Gas? A ghost?"
Fred took a few minutes to find his voice, his chest heaving. "It's... it's upside down," he wheezed. "The second you step in, the world flips. I was walking on the ceiling, but there were these... stone spikes. Millions of them, like a forest of needles pointing right at my head. I felt like if I took one wrong step, I'd fall up and be skewered like a kebab."
Lee and George exchanged a nervous look. "An inversion trap," Albert murmured. "A classic disorientation charm, likely reinforced with a heavy-duty illusion."
"Illusion?" Fred snapped. "It felt pretty bloody real to me!"
"Think about it, Fred," Albert said, his mind already dissecting the mechanics. "A thousand-year-old mist. It's designed to test your mental fortitude. If you close your eyes and run, you probably won't feel the gravity shift. It's your brain trying to process the visual data that causes the panic."
"Run with my eyes closed?" Fred barked. "Into a tunnel I've never seen? You're mental."
Fred tried a small experiment. He stood at the edge, shut his eyes tight, and poked a foot in. He didn't feel himself flip. "You might be onto something," he admitted, though he still looked shaken.
"This is Gryffindor's test," George said, looking into the fog with newfound respect. "He didn't want someone who could just solve a puzzle. He wanted someone who could look at a forest of spikes and keep walking anyway."
"So, we just close our eyes and hope for the best?" Lee asked.
"No," Albert said firmly. "That's a coward's way out. And knowing Godric, he'd have a trap waiting specifically for people who try to 'cheat' the test. If you can't see where you're going, you're just asking for a pitfall."
"Why don't you go then, if you're so sure?" Fred challenged, still feeling the phantom sensation of falling.
"I plan to," Albert said. He didn't bother with the rope. He adjusted his robes, took a steadying breath, and walked directly into the violet mist.
The transition was violent. One moment he was on solid ground; the next, his stomach lurched into his throat. His vision spun three-hundred and sixty degrees until his feet were firmly planted on what should have been the ceiling. Below him—or rather, above him in the real world—was a terrifying vista of jagged stone cones. They glittered in the dim light, looking sharp enough to pierce dragon hide.
His legs betrayed him for a second, a sharp tremor running through his thighs. It was one thing to theorize about an illusion; it was another to see your impending death inches from your skull.
But Albert didn't close his eyes. He forced himself to look. He noticed that the corridor wasn't dark. Every few yards, a bracket on the 'floor' held a flickering blue flame.
"Gubraithian Fire," he whispered. "Everlasting."
He began to walk. It was slow going. Every step felt like a leap of faith. The 'ceiling' he was walking on was smooth, but he kept his eyes locked on his own boots. After a few minutes, he reached the first real obstacle.
A gap in the path.
It was a pit, about four feet wide, cutting across the entire corridor. In the inverted world, it looked like a bottomless hole leading into the stone spikes below. If he had been walking with his eyes closed, he would have stepped right into it and plummeted.
"Clever," Albert thought. "The 'brave' person walks through the illusion. The 'smart' person closes their eyes. The 'smart' person then falls to their death."
He took a running start and jumped. For a split second, he was weightless, hanging over the spikes, his heart hammering against his ribs like a trapped bird. Then, his boots slammed onto the other side.
He encountered two more of these pits over the next ten minutes. Each jump was more nerve-wracking than the last, a test of pure, unadulterated nerve. By the time he reached the end of the violet mist, his heart was racing and his cooling charms were working overtime to handle the sweat.
He stepped out of the fog into a small, circular stone chamber. The gravity snapped back to normal so suddenly he had to catch himself against the wall.
He stood there for a moment, his legs still shaking, a grin slowly spreading across his face. "Typical Gryffindor," he laughed. "Absolutely mental."
He knew Fred and the others were likely debating whether to follow him or head back to the castle. He couldn't just leave them there, and he didn't want them falling into the pits.
He reached into his extension bag and pulled out his broomstick. It was a simple solution, really. He mounted the broom, kicked off, and flew back into the mist. But this time, he flew upside down, matching the inversion of the corridor.
Flying through the mist was much easier; the broom's enchantments helped stabilize his inner ear. He hovered just inside the entrance, his head hanging 'downward' toward the twins and Lee.
"It's not an illusion you can ignore!" Albert shouted to them, his voice echoing out of the fog. "There are pits in the floor. If you walk through with your eyes shut, you're dead. Get your brooms. If you fly through upside down, your brain won't fight the gravity shift as much."
