Chapter 1: Awakened in the Light

Darkness. An eternal, consuming darkness.

Then, a spark. A distant, cold light seared through the void, casting spectral rays over fragmented memories. Echoes of a life, a world called Remnant, splintered and faded. The weight of forgotten time pressed against her consciousness until a single voice cut through the emptiness.

"Guardian. Eyes up, Guardian."

Weiss's eyes snapped open, a piercing blue glow reflecting the cold, barren environment around her. The air was sharp and frigid, carrying the biting winds of a shattered world. Snowflakes drifted down like a haunting lullaby, their dance mocking the stillness of the ruins.

A small, star-like figure hovered before her, its single blue-white eye shimmering with curiosity and urgency. The floating machine's shell unfurled briefly in a whir of motion before it settled again.

"Oh, good. You're awake," the little robot said.

Weiss's throat was dry, her voice a strained whisper. "Who... what are you?"

"I'm your Ghost. Call me Nix," the Ghost said. "We're going to have to skip the introductions for now—the Fallen are here. We need to move." The urgency in Nix's tone cut through her confusion.

She pushed herself up, her muscles protesting. Her body felt unfamiliar, like a porcelain doll regaining motion. As she stood, her gaze fell to the ground—a rusted, broken blade lay at her feet. Myrtenaster. Or what was left of it. Her heart twisted.

"How long was I... unconscious?" she asked.

Nix hesitated. "You weren't unconscious. You were dead."

The words struck her like a hammer to the chest. Dead? Her mind raced to reconcile that statement. Flashes of a bullhead, a descent into Mantle, then... nothing. An abyss where memory should have been.

"But..." Weiss tried to form coherent thoughts. "Beacon. Ruby. My team... Blake, Yang."

"That's... unusual," Nix said, a note of surprise in his voice. "Guardians don't usually remember their past lives. But right now, we need to survive."

A guttural, alien snarl echoed through the skeletal ruins. The air crackled with static electricity. Weiss spun around, her eyes narrowing as shapes moved through the shadows. Six-limbed creatures with glimmering armor and electric weapons—Fallen.

"We need a weapon," Nix said urgently, his eye scanning the area.

Weiss's hand reflexively reached for her side, but her weapon was gone. She gritted her teeth, forcing down the rising panic. Nix darted away, disappearing behind a collapsed wall. Moments later, he re-emerged.

"Here!" he called. "It's not your rapier, but it'll do."

Weiss approached and found a rifle lying in the frost-covered rubble. The weapon was battered but functional. She lifted it, the weight foreign and uncomfortable compared to the elegance of Myrtenaster.

A Fallen Dreg hissed, its cracked mask glowing faintly. It lunged at her, twin blades buzzing with Arc energy. Instinct took over. Weiss raised the rifle, her finger tightening on the trigger. A burst of gunfire erupted, each shot punching through the creature's armor. The Dreg collapsed, dissolving into etheric mist.

Her breath came fast and shallow. "This is not how I fight."

"It'll have to be," Nix said. "Come on—we have to reach the Cosmodrome. There's a jumpship there. If we can get it running, we can reach the Last City."

"The Last City?"

"Humanity's final stronghold. Your new home." He paused, his tone softening. "Trust me, Weiss. I'll explain everything once we're safe."

She nodded reluctantly, the icy winds biting through her tattered clothing. The reality of her situation was starting to solidify—she was no longer on Remnant. This was a different world, a different war. But she'd always fought to protect those who couldn't protect themselves.

And she would do so again.

Nix flared his light, illuminating a path through the ruins. Weiss tightened her grip on the rifle and followed. The darkness pressed in from all sides, but she held onto that spark, that faint glimmer of purpose.

She was a Guardian now. Whatever that meant, wherever it led—she would not falter.

As they crested a hill, the horizon opened to a sprawling graveyard of rusted spacecraft. The Cosmodrome stretched before them, a desolate land littered with the wreckage of a forgotten Golden Age. Lightning crackled in the distance, and the air hummed with unseen threats.

Nix's voice was steady. "Eyes up, Guardian."

Weiss took a deep breath, ice and fire swirling in her veins. She looked out at the battlefield, the endless sky beyond it. A new beginning forged in Light and shadow.

"Let's finish this."
