Iron Bonds: Pandora's Box - part 1

What if the Avengers world and Uncharted were combined into one?

A world where Tony Stark had a little sister, and Nathan Drake used to date her. As they both went through university together, to become the best in their feild. But after things got serious between them, Alex walked away from Nathan, and vowed never to let anyone get close to her heart again.

What if Tony Stark had a little sister, that unlike him, didn't like to be in the public eye as much as he did. Alex grew up watching films like Indiana Jones and Tomb Raider, which instantly gave her the idea of what she wanted to do with her life when she grew up.
Alex became an archeologist.
She found this life exciting and was full of adventure.

However, little did Alex know, her life was about to turn upside down, when a group, called the Obsidian Order, was after the myth of Pandora's Box.
But what if this wasn't just a myth?
What if this box really existed. And could cause the destruction of the world?
The Obsidian Order had believed Thanos to have the right idea, and had been looking for a way to "help" humanity.
Alex can't let that box get into the hands of such cold hearted people. The only way to stop them, was to put her differences aside with her big brother, who she hadn't spoken too in months, and go out there, find Pandora's box, and stop them.
