The portal swirled around Alfie and Dad like a washing machine made of rainbow bricks, spinning them through the space between dimensions. Alfie squeezed his eyes shut, still thinking about the Hollow—that faceless shadow that wanted his Infinite Brick.
WHOOSH!
They landed with a soft thump on something springy. When Alfie opened his eyes, he gasped.
They were standing on a massive LEGO training mat, bright red and perfectly smooth. All around them rose the walls of an enormous dojo—a karate training hall built entirely from white and black bricks. Paper lanterns made of transparent pieces glowed softly overhead, and wooden training dummies stood in rows like patient students.
"Well," Dad said, brushing off his knees, "this is different from the water world!"
"Alfie! My young Guardian!"
A familiar voice echoed across the dojo, and Alfie's face lit up like a Christmas tree. Striding toward them came Captain Skull Fire himself—his flaming skull head crackling with warm orange light, his black ninja suit swishing with each step.
"Captain Skull Fire!" Alfie ran to his old mentor and hugged him around the waist.
"I sensed you needed guidance," Captain Skull Fire said, kneeling down. His flames flickered gently. "This is the Discipline Dimension—and you're here for a reason, young one."
Before Alfie could ask what reason, something strange happened. The air in front of him shimmered like heat rising from summer pavement, and a figure stepped out of nowhere.
It was... him.
A shadow version of Alfie, made entirely of swirling grey mist, stood on the mat. It had Alfie's shape, Alfie's height, even Alfie's messy hair—but it wouldn't stop moving. It bounced from foot to foot, waved its arms around, and kept making silly faces.
"What IS that?" Dad whispered.
"Your Mirror Shadow," Captain Skull Fire said seriously. "It shows the part of you that struggles to focus. The part that wants to muck around instead of train."
Alfie watched his Mirror Shadow attempt a jumping jack, but it only did half of one before flopping onto the mat and rolling around.
"To earn your orange belt," Captain Skull Fire continued, "you must train here. But your Mirror Shadow will copy everything you do—only sloppily. If you cannot bring it under control through your own discipline..."
"What happens?" Alfie asked nervously.
"Then you will never master yourself. And the Hollow..." Captain Skull Fire's flames dimmed. "It feeds on chaos. On unfocused minds. Your Mirror Shadow is exactly what it's hunting for."
Alfie's tummy did a flip. His orange belt grading was coming up soon, and he really, really wanted to pass.
"Okay," he said, taking a deep breath. "Let's train."
Captain Skull Fire nodded proudly. "Begin with your warmup. Twenty pushups."
Alfie dropped into position and started. "One... two... three..."
His Mirror Shadow flopped down too—but it just lay there like a pancake, wiggling its arms uselessly and giggling.
"Four... five... six..."
"Focus only on yourself," Captain Skull Fire instructed. "Your discipline will teach it."
By pushup fifteen, Alfie noticed something amazing. His Mirror Shadow was actually trying now—still wobbly, but trying.
"Running laps!" Captain Skull Fire called next.
Alfie jogged around the dojo. His Mirror Shadow kept stopping to look at butterflies (made of LEGO, of course), but when Alfie kept his pace steady and his breathing calm, the shadow eventually followed.
Then came the real test: combinations.
"Front punch! Low block! Round kick!" Alfie called out his moves, snapping each one with focus.
His Mirror Shadow tried to do a silly dance instead.
"No!" Alfie said firmly—not angry, just focused. "Watch me. Like this."
He performed his kata—the special pattern of movements—slowly and carefully. Step, block, punch, turn, kick. Each move flowed into the next like a river.
And slowly... his Mirror Shadow began to copy him. Not perfectly. But better.
"You're doing it!" Dad cheered from the sideline.
But just as Alfie felt proud, the lanterns flickered. A cold wind swept through the dojo, and in the doorway appeared something that made Alfie's heart freeze.
The Hollow.
It had no face, no features—just an endless, hungry darkness shaped like a person. And it was pointing directly at Alfie's still-chaotic Mirror Shadow.
"Yessss," the Hollow hissed. "Such delicious disorder. Give me the unfocused one... and I'll leave you alone."
Captain Skull Fire stepped forward, flames blazing. "Alfie—whatever you do, don't let it take your shadow. If you lose that part of yourself..."
"You'll never be whole again," the Hollow finished, laughing like wind through empty buildings.
Alfie looked at his Mirror Shadow, still bouncing nervously, and made a decision.
He wasn't giving up ANY part of himself. Not to anyone.
But how do you protect something that won't stand still?
