Chunk of your shoulder is missing, the zombies got you. I's a mystery how you're still able to walk with that much blood loss. you drag your self into your sanctuary. in there is a box where you keep your emergency supplies. you dig through them and pull out the green herbs. you fumble with it for while. you're not exactly sure how to use the herb. eventually you manage to apply it to your wounds and it soothes you instantly. You still don't know how it works.
