We landed in a world stripped of technology, its streets bustling with simplicity. As we wandered, we encountered a man I recognized - a figure who had collided with Hawkeye during the Avengers' celebratory walk. This time, his presence felt deliberate.

"You're not supposed to be here," he said, his voice low and foreboding.

The pieces of the puzzle began to fit together. The girl traveling with us wasn't just anyone - she was Valkyrie herself, bound to the blades Thanos sought. The man who had abducted the scientist and the girl was Hawkeye, operating under orders from a future timeline.

And Thanos? He wasn't the villain we believed him to be. His mission was to prevent a greater catastrophe, one that required three artifacts: the Infinity Gauntlet, the Valkyrie Blades, and a third, unknown piece.

The revelation hit me hard: I was at the center of this paradox. My actions had set these events into motion, and now the fate of countless timelines rested on our shoulders.

As we stood in the dimly lit street, the man spoke again. "You don't understand the stakes yet. The third artifact isn't an object - it's a person. And they're already here."

Before I could respond, a blinding light filled the sky. A massive spacecraft descended, its silhouette eerily familiar.

The fight wasn't over - it was only beginning.
