Imperium - Forged in Fire

All he wanted to do was tinker in a lab. Figure out why things worked like they did and how to design new tech to interact with the physics. Things were going well except for a couple of hiccups, like being elected to a management role he didn't want.
Then he met her.
His life was turned upside down - suddenly he didn't just want to build new stuff, he wanted to share it with her. She wanted to be part of his life. Things were going so well fate had to step in, so they happened across an ancient enemy who also just wanted to annihilate every human everywhere. And so it goes.
