I recently unlocked Mythshore and failed the Perception 10 check and the event tells me to follow the survivors but I'm stuck, how do I continue?
I reread what you wrote. There should be a route available for you to follow. The goal is to get to the upper left corner of mythshore. If you can't back up or go anywhere, reload a previous save. If you can, get to around level 10 perception then back up and go back to your spot. I recommend using a focus tea, the Christmas gag collar, and the lizard-man blessed piercing to help since all of these should raise perception and you get them pretty early game.
