Personally, I'd prefer to believe that the Dark Gods have the great hand in this. They are the ones that give the power to the humans, in turn must those people go to the other side of the world. Why up? Well, I personally doubt any of this was really thought out at all by the creators, but a spiritual being, such as a magician, animated suit, or a alter-dimensional priestess, this kind of creature would naturally have his or her spirit cast upwards, like much of human religion and philosophy seems to suggest for all spirits.
About the Dark Gods, Sili, are you on the bandwagon with Forrest and I? conform… Conform … CONFORM …
:-P
