There exists a small circle of trees somewhere in the Rocky
Mountains, completely unremarkable from the outside, but
just inside no sun or star ever shines. Rumor has it that
anyone that can spend three pitch black days and nights
within the grove without going mad will be greeted with the
queer sight of the sun rising in the west on the beginning
of the forth day, filling the grove with radiant light. One
wish may be made before this sun, and it shall be fulfilled.
However, once that person makes the wish, the world outside
the grove shall forever be as dark for them as it had been
inside for those three days.
