Here you were, you don’t know how you got here, you don’t know why this happened, all you know is that the world had ended. It is winter now and you had built up a small fire inside this old cabin you found to keep warm. Alas after a few days a stranger shambles inside and collapses in a corner, she looks near frozen, to make things worse your wood is running dry, best to go scrounge up some sticks from the surrounding forest
