The Middle lands

When a soul dies you go to Heaven or the Underworld, but what happens to the soul that could make it to ethier? In the Nightscape/Mindscape, souls of the dead that feel unworthy or unwanted redeem their fate fighting the Phobia beast and protecting the minds of all ages to bend the fears and help their fate so the soul can remain at peace;however if the soul bends the rules and joins the darkside they will be sent under.
