A forest covered in tall pines. The forest is inhabited by tons of eevees and their evolutions. Bu the forest is blocked off to any trainers by a mysterious mist that covers the forest. And if any trainer happens to go into the mist they'll just go in a circle back to where they came from. There is also a guardian of the forest that has guarded it for many years.
A lake in the middle of the Evolution forest. Its water is said to heal the wounded. But it is polluted so it has no effects on anything. With the help of Suicune it may become clear again.
