In the midst of the depths, you thought you were all alone with the fishes and sea horses. You thought wrong.
Today, a stranger will approach your newly created shelter. That person has all the same abilities as you and has been given directions to survive just as you have. The only difference between you two speak different languages. It is your choice if you want to take this stranger in and help them, but you both must survive.
Consider that you have been able to survive on your own for this long already. Can you support two people and house another person in your modest shanty?
Remember, success in this game depends upon both of you surviving, but it your choice on how you want to accomplish that goal.
