See the attached document giving details on handling auras, specifically as related to the three religions in this saga.
In a +6 magical aura people get weird when they spend more than a few seasons there, over the long term. Given the fact that people have been living in the Mountain for generations it is no surprise this has taken place. If outsiders start living here long-term, and breeding, expect weirdness to happen, but not necessarily along the same pathway.
Children born and raised in a +6 aura have one extra point of Virtue and two extra points of Flaws as grogs. These extra points must be mystical in nature. This applies to all inhabitants of the mountain.
A common flaw, Unusual perceptions, is worth -1 and involves peculiar aesthetics: the unusual, bizarre, and even horrifying becomes aesthetically interesting to the inhabitants. Magi with the Blatant Gift find themselves being treated as if they had the Curse of Venus instead, little girls pester Criamon magi for tattoos, children are drawn to and fascinated with magic (and will often ask magi to do some magic for them or to them). Grogs with this Flaw will have trouble in social interaction with mundane ones.
Occasionally, within very special supernatural areas, special types of auras arise. These may exist within larger domains or by themselves, and may be of any type of aura. They are called regiones (singular regio, "realm"). Unlike other auras, regiones form self-contained worlds unique to the realm that they are aligned with.
At their extreme regiones are more a psychic landscape than a physical one, a journey through one can be a journey into the inner space of a human being and humanity in general. The external terrain does not, in a sense, exist in its own right but as a material indication of internal desires and fears; it is the kind of space that Manuel Aguirre calls a "labyrinthic Forest" that "symbolizes the realm of lawlessness: inimical, yet rewarding, populated by white stags and other fantastic creatures, full of dangers yet full of praise too." (Manuel Aguirre. The Closed Space. Manchester, Eng.: Manchester U.P., 1990) As would be expected in such a psychomythic landscape, normal Euclidan geometries of space, motion and time are no longer applicable; the traveler would move out of quantifiable objective reality into a "boundless expanse of unprecedented uncertainty, with apparently no inside and no outside...." (Jung, The Archetypes and the Collective Unconscious, p 21) Perceptions, most especially of the self are expanded as the individual "emerges from profane, chronological time and enters a time that is of a different quality, a 'sacred' Time at once primordial and indefinitely recoverable (Eliade, 18)
This is a beginning point for explaining the higher level regiones, and the realms, if any, that lie beyond them. Those realms should never be reduced to mere mechanics. Lower level regiones partake of this essence, serving as the bridge between the everyday world and the Mythic. A trip into even the lowest of regiones should be an event to remember, full of epic qualities. In short regiones should always have the aspects so beloved of Marchen.
