From the moment you are born in the middle of
your own Circle, the green and red man will
guide you in your new world. Within your
Circle, the green man encourages you to go your
own way and discover your borders, while the
red man says "stop" if you threaten to cross that
border.
But if you have ignored the signal of the red man
and 'accidentally' crossed that border, they turn
their roles. Outside your Circle, the red man
seduces you to discover your new border at the
end of the world. And while step by step its
getting darker and colder, you can vaguely hear
the green man say "stop".
