Summary
Celeste: A Marvel UntoldCeleste Astra Vale, known to most as Celeste, never asked to be a hero. She’s just trying to find her place in a world that’s constantly in chaos. As the Avengers face their biggest battles in Infinity War and Endgame, Celeste finds herself caught up in the action, but it’s the quiet moments, the personal connections, that matter most to her.At the heart of it all is Bucky Barnes—her complicated, powerful, and sometimes frustrating bond with him that’s unlike anything she’s ever known. As they navigate the battles and losses of the MCU, Celeste and Bucky’s journey is about more than just surviving the world around them—it’s about discovering who they are together, one step at a time.(Please note that the summary might not be intresting or correct with the whole fanfiction due to it still being ongoing and written. Yes the chapters aren't that long even if there might seem to be many they are quit short. There is time skips, and it does follow the movies of the infinity saga in Marvel, but only a few of the movies.)

The Assembled Fate

Time had passed, but Celeste still felt like she was waiting for something—some sign that she truly belonged in this new world.

She had been on missions, faced threats that weren’t so different from the ones she had fought decades ago, but something was shifting. There was a tension in the air, an unspoken weight pressing down on S.H.I.E.L.D. that no one dared to name. And then, the call came.

Loki.

A name she barely recognized, a threat she didn’t yet understand. A stolen artifact, destruction in his wake, and an arrogant smirk that made her fingers twitch at her sides. Fury’s orders were clear—she was being pulled into something bigger than anything she had faced before.

Meeting the Team

The Helicarrier was unlike anything Celeste had ever seen. A floating fortress in the sky, filled with the best of the best—people who, in one way or another, didn’t quite belong anywhere else either.

And then there was him.

Tony Stark. Larger than life, sharp-tongued, and with an ego that filled the entire room. He sized her up in seconds, smirking as he quipped, “You’re not on the historical exhibit tour, are you?”

Steve stood beside her, arms crossed, ever the soldier. “She’s with us.”

“Right, the other relic.” Tony’s eyes flickered over her before he gave a casual shrug. “You at least got any cool powers, or are you just another super-powered grandparent?”

Celeste arched a brow. “Wouldn’t you like to know.”

Natasha, standing at the side, hid a smirk.

Then there was Bruce Banner, whose quiet presence intrigued her more than the rest. He had an aura of something restrained, something buried deep, much like herself.

And Thor—the god. His presence stirred something in her, a flicker of memories she couldn’t place. She had met gods before, hadn’t she? Or maybe she had once been considered one. His gaze lingered on her, as if he, too, sensed something familiar. But there was no time for questions, not now.

The Rising Storm

The mission was clear—Loki had to be stopped. The stolen Tesseract was a threat beyond comprehension, and as the team moved into action, Celeste found herself slipping into place as if she had always belonged there.

But tension ran high. The team was fractured, arguments brewing between Stark and Steve, distrust running through every conversation. She was used to battlefields, to clear enemies and strategies. But this? This was a war of egos just as much as it was a war for survival.

And then, just when it seemed like they might find a rhythm—Loki struck. A brutal attack, chaos erupting in the Helicarrier, and Celeste found herself face to face with something terrifying.

The storm was only just beginning.
