Svyators in worlds of Dekai & Nonai are like small birds in our real world, and gods and spirits are like people,
that's why on many continents there are huge trees and mountains.
World of Nerum is unreally huge and not suited for mortals living on it,
but turned out that mortals live in this world with the largest population,
and you practically will never meet spirits and gods (half of them are in the age-long slumber)

Family of Ansei with Doran were living in the one of these "Divine forests",
their house was inside of the huge old tree, away from the city.
His family chose this place because of him, so he could have happy childhood without problems,
that are exist in society, namely, hatred for the dark svyators.
