The chamber trembles with the sound of chains rattling.

Restrained at the center of the room, {{user}} fights against bindings that were never meant to hold something like her. Uru-reinforced restraints bite into her wrists and ankles, glowing faintly as they try—and fail—to suppress the power rolling off her in violent waves. Her breathing is sharp, uneven. Energy crackles across her skin like a storm searching for a sky.

“Hold her steady!” a SHIELD agent shouts.

She thrashes harder.

The air warps. Lights flicker. One guard stumbles back as an invisible force slams into him, sending him skidding across the floor. Alarms whine, red warning lights pulsing.

Then the blast doors slide open.

The Avengers step in as one.

Steve Rogers is the first to assess—eyes sharp, shield already half-raised. Natasha’s gaze flicks from the chains to the guards to {{user}} herself, calculating. Clint’s bow is in his hand before he realizes it. Wanda freezes, hand lifting to her chest as something pulls at her senses—ancient, familiar, wrong and right all at once.

Peter Parker swallows. “Uh—guys? She’s… not human. Like. Really not human.”

Tony’s eyes are locked on the readings scrolling across his HUD. “That energy signature? It’s not cosmic. It’s not gamma. It’s not anything I’ve ever—okay, that’s officially annoying.”

Bruce Banner squints at the monitors. “That’s… impossible.”

Thor stops dead.

The room seems to hold its breath.

The lightning outside the chamber’s reinforced ceiling answers him instinctively, a low rumble echoing through the walls. Thor’s grip tightens around Mjölnir. His face drains of color.

“No…” he breathes.

Beside him, Loki has gone utterly still.

Not smug. Not amused. Not calculating.

Stricken.

His eyes lock onto {{user}} like he’s staring at a ghost that never truly left him. The air around him hums, magic reacting before thought.

“That energy,” Loki says quietly, dangerously soft. “I would know it anywhere.”

{{user}} jerks against the chains again, head snapping up at the sound of his voice. Her eyes—bright with fury, pain, and something heartbreakingly familiar—find them.

For half a second, the struggle stops.

“Thor?” Her voice is hoarse. Disbelieving. “Loki?”

Thor moves before Fury can stop him.

“Thor—wait,” Steve starts, but Thor is already stepping forward, eyes shining.

“It is her,” Thor says, voice breaking under the weight of relief and grief colliding. “By the stars… it is you.”

Loki’s composure finally shatters. “They chained you,” he snarls, magic flaring like a blade drawn too fast. “They put you in irons.”

Fury raises a hand. “Easy. That ‘you’ nearly tore through three containment teams. We didn’t know what we had.”

“You took my sister,” Thor growls, lightning licking across his shoulders, “and called it containment.”

Around the room, weapons lower—slowly, uncertainly.

Carol Danvers tilts her head, studying {{user}} with new interest. “You’re Asgardian.”

“More than that,” Wanda whispers, eyes glowing faintly as she feels the echo of something old, royal, and wounded. “She feels like… legacy.”

Shuri’s fingers fly over her kimoyo beads. “Those restraints were designed for gods,” she murmurs. “And even then, they’re failing.”

Tony exhales. “Great. Another secret god sibling. Do we get a punch card for this?”
