Author's Note: FINALLY. I know this story has been a long time in coming. I hit a wall with writing for quite awhile, but watching the Endgame trailer inspired me! [It also crushed my soul into a million tiny pieces, but that's beside the point.] So, thank you so much for reading. If you've made it this far in my series, that is amazing! I'm excited to dive right into the heartbreak and horror that is Infinity War. I'm going to try to post weekly. I'm horrible at sticking to deadlines like that, but I'm going to try my best!

Part One: Reality

Prologue – Unknown Date

There were an infinite number of possibilities. She'd always known that. Always known few would lead to an ending where the universe remained intact, where everyone she loved didn't die. She didn't realize there was only one. Didn't know what it would cost. But now, at the end, she knew, and she wished she could take it all back. The cost of saving the world had always been steep, but this was too much. This time the universe had taken too much, and she wasn't sure she could get it back. Here at the end of all things, she looked back on her life and wished she could have had more time. She'd wasted so many years. If only she could turn back time. Time was all it would take to fix what was broken, to give her what she needed before the end was truly here. The price was too much but, despite it all, she knew she was willing to pay it because that was when heroes did. They sacrificed everything until all that was left was good intentions and the rush of blood in their veins. Until they were standing alone at the precipice of a place they couldn't come back from. That was the sacrifice she would make because anything else, any other possible outcome was an illusion. This was reality, and it was time to face it.
