We've got something pretty big going down in about two hours. Everyone needs to use their passports and get off the head, stay off for the next eight or so hours. It's safer that way.
Anyone who stays behind when this goes down is risking sterilization. It's not a guarantee but it's a possibility. If that's not something you're worried about, feel free to stay behind and help us. But if it is, you need to leave in the next two hours. Now's a great time to visit Earth and get yourself something to eat. If you haven't used the passports before, find someone who has and they can help you.
