Mount Terror

We often wonder where did our stories of Mythological creatures come from.  Were they the imagination of the mind that created such creatures as Centaurs, Dwarfs, Satyr's, Ogres, Goblins, Fairies, Sprites, Kobolds, Kelpie, Harpies, and so many more Mythological creatures of legends from ancient times from different cultures.  The Dragon from ancient Chinese culture.  The Dwarf from Germany.  The Kelpie from Scottish culture.
Even in American Native Indian folklore, we have Deer Woman, and Elk Man human upper bodies and lower bodies of a Deer or Elk.  Creatures that tended the welfare of the forest.  Are such Mythological Folklore fiction or non-fiction?  Are magical creatures fiction or non-fiction?  Is it even possible these creatures exist on other worlds in our universe?  On Earth we have Mythological creatures and deities that represent Good and Evil.  Creatures with evil magic and creatures with Good magic and the two do not get along.  In Mount Terror we have a story of two worlds where in one world such Mythological creatures exist and so does Good and Evil.  In this world the Evil One, has been imprisoned for a thousand years and soon will escape his prison.  When he does he will discover the second world is just finding out its source of magic from its folklore returning.  The Evil One feeds on good magic and evil magic until he has consumed the source of magic in the world, destroying the world environmentally.  Earth may be his next target, unless two Earth teens, a Goblin, and a Satyr from Polaruis can stop the Evil one from escaping his prison.
