OtherWorld

This world was created in tandem with another world, Domhan, the home of the human race. Here reside peoples that human mythology refer to as spirits, sidhe, dokkaebi, lwa, kami, and vættir. These two worlds, though very different in many ways, also had a tendency to overlap and twin each other. In some of these overlapping places there was a thin, misty veil that allowed people to pass from one world to another, especially during certain times of year.
Long ago the veil stopped allowing passage and the worlds have been separated, irreparably it seems. Since then the residents of the Otherworld provinces (such as Tir n'Aill, Jeoseung, Asamando, Ásgarðr, Guiné, Tokoyo no Kuni, and innumerable others) have continued to grow and evolve while the histories of Domhan have faded into myth and legend.
