Chapter Text
The Sonoro Sphere shouldn’t have sounded like that.
Rover had heard plenty of distortions before — echoes humming under ruined cities, memories fractured into sound, the quiet ache of resonance lingering in the air like a fading heartbeat. But this one was… wrong. Not chaotic. Not corrupted.
Just vast.
The sphere hovered before him, shimmering with layered frequencies that overlapped like waves crashing into each other from different oceans. Its surface reflected not the world around him, but fragments of someplace else — streaks of purple starlight, unfamiliar constellations, metal corridors shaped like curved blades.
He frowned.
“Yeah,” he muttered to himself, hand hovering over the hilt at his side, “that doesn’t look suspicious at all.”
The sphere pulsed in response.
Rover sighed.
Then stepped forward.
---
The moment his hand touched the surface, resonance surged through his veins like lightning.
Sound collapsed into silence.
Gravity vanished.
And then—
He fell.
---
Stars stretched around him like rivers of fire. Rover tumbled through weightless dark, fragments of energy spiraling past his body. The Sonoro Sphere shattered into motes that dissolved into the void, leaving him suspended between unfamiliar constellations.
His resonance tried to anchor him, but there was nothing to grasp.
No echoes.
No land.
No sound.
Just the terrifying realization that wherever he was… it wasn’t his world.
A distant roar broke the silence.
Not organic.
Mechanical.
Massive.
Rover twisted mid-fall and saw it — a towering form cutting through space like a living weapon, glowing lines tracing the shape of a colossal lion made of metal. Blue energy flared from its thrusters as it surged toward a fleet of alien ships.
He blinked.
“…That’s new.”
Before he could question reality further, gravity returned all at once.
Rover plummeted.
---
Blue Lion’s cockpit alarms screamed.
“Uh — guys?” Lance leaned forward, eyes wide behind his visor. “Tell me I’m not seeing a random dude falling through space.”
“That is exactly what you’re seeing,” Pidge replied, fingers flying across her console. “No suit, no thrusters, no life support. That should be impossible.”
Keith’s voice cut through the comms, steady but tense. “He’s on a collision course with the battlefield.”
Hunk winced. “Okay, that’s definitely not good.”
Shiro’s tone shifted instantly into leader mode. “Lance. Intercept. Now.”
“On it!”
Blue Lion surged forward, claws glowing as Lance angled beneath the falling figure. With a careful burst of thrusters, he caught the stranger in the lion’s energy field just before impact.
The alarms died down.
Silence filled the cockpit.
Lance stared at the unconscious boy floating in the containment glow — dark hair drifting weightlessly, expression oddly peaceful despite the chaos he’d fallen through.
“…Okay,” Lance said softly. “Either I just rescued a space angel… or we’ve got a lot of questions.”
---
Rover woke to warmth.
Which was confusing, considering the last thing he remembered was freezing vacuum.
His eyes opened slowly.
The first thing he saw was a curved ceiling lit with soft blue light. The second was a face hovering way too close to his own — tan skin, blue eyes, and an expression caught between curiosity and panic.
Rover blinked.
The stranger blinked back.
“Hi,” the stranger said. “So, quick question — are you secretly an alien who can survive space, or are we about to deal with a medical emergency?”
Rover stared at him.
“…I have absolutely no idea where I am.”
The boy groaned. “Yeah, that tracks.”
---
The common room aboard the Castle of Lions felt quieter than usual.
Rover sat at the center of a semicircle of strangers who clearly knew each other very well — their familiarity obvious in the way they stood, spoke, and interrupted one another without hesitation.
A tall man with a calm, commanding presence stepped forward first.
“I’m Shiro,” he said gently. “You’re safe here. We found you drifting in space near an active battle zone.”
Rover processed that sentence.
“…You found me where?”
“That’s what we’d like to know,” Keith said from the wall, arms crossed, eyes sharp with suspicion.
Hunk offered an apologetic smile. “Sorry, he does that with new people.”
“I don’t,” Keith muttered.
“You absolutely do,” Lance whispered.
A girl with round glasses pushed past them, scanning Rover with a handheld device. “Vitals are stable. No Galra tech implants. Resonance readings are—” She paused, frowning. “Weird. Like… really weird.”
Rover tilted his head. “Resonance?”
Her eyes lit up. “You know what that is?”
“Where I’m from,” Rover said quietly, “it’s part of everything.”
The room fell silent.
A graceful figure stepped forward then, her presence commanding yet warm. Flowing white-and-blue garments shimmered faintly under the lights, and the crown atop her head marked her as something more than a teammate.
“I am Allura,” she said. “Princess of Altea and pilot of the Castle of Lions. And this is Coran, my royal advisor.”
Coran bowed with theatrical flair. “At your service, mysterious space traveler!”
Rover hesitated, the weight of unfamiliar stares settling on his shoulders.
“…Rover,” he said finally. “That’s what people call me.”
Keith’s gaze sharpened. “You don’t know your real name?”
Rover met his eyes.
“No.”
Something unspoken passed between them — a quiet understanding forged from shared fragments of lost pasts.
Shiro noticed it too.
“Well,” Shiro said gently, breaking the tension, “Rover, until we figure out how you got here… you’re welcome to stay with us.”
Lance grinned. “Plus, anyone who survives raw space entry deserves at least one decent meal. Hunk?”
Hunk was already halfway to the kitchen. “I’ve been waiting for you to say that.”
Rover blinked, caught off guard by the warmth.
Different world. Unknown stars. No path home.
And yet…
For the first time since falling through the Sonoro Sphere, the tight knot in his chest loosened.
Maybe this universe wasn’t entirely hostile.
Maybe.
But as faint resonance stirred deep within him — echoing not just his own power, but something ancient humming through the lions themselves — Rover couldn’t shake the feeling that his arrival hadn’t been an accident.
Somewhere beyond the stars, fate had answered his call.
And it was only beginning.
