Setting: Before the game
Current plot: Our Twins are/going to be separated from their tribe as they migrate to Aloy's Village. We've decided that a hunt goes wrong, probably due to MC. Oops.
After that, it'd be a journey to find their tribe. We can encounter ruins, other tribes, and even create fictitious settings. I hate to be so general, but the setting is enormous.(Did we want a little dog like machine thing to accompany them?)
Backstory: Agreed that we wont set anything in stone, and that all we come up with are just the individual character's theories.
