Sanctuary of Twos

It was two years ago you met.

Two years ago and your life was so incredibly different. You would have sworn the world, and anything worth living for, was gone. The apocalypse took everything away from you, your family, your friends, your job. And it all came so suddenly you couldn't even get the closure you needed. The pain you felt when you tried to think about the life you had wanted to be leading and the people you would be leading it with by now seared through you like a branding iron the moment it entered your mind. Thinking about it wasn't an option if you wanted to keep putting one foot in front of the other.
Open space in broad daylight was one of the most dangerous places to be after the Gratics arrived.

Large robotic alien lifeforms, starting at 9ft tall, the Gratics as they called themselves, with unmatched weapons of mass destruction easily obliterated the colony you called home. You never found out why. Only that they didn't seem to be targeting civilizations so much as clearing spaces that were ideal for building mines. You had no idea what was so valuable that it was worth destroying so many lives for. You had nothing to lose and a few humans left who wanted answers so 'fuck it' you thought to yourself 'let's go steal some unknown robot ore.'
