A heroquest is a direct interaction with the divine realm of myth and archetypes. In a heroquest, you interact and experience the divine realm and bring back magic, be it Rune spells, guardian spirits, good harvest, a terrible curse, something long forgotten and hidden, etc.
As we interact with the kaleidoscopic divine realm, we of course change its arrangement. Like walking into a room of swirling smoke, our presence causes the mist to swirl around us, changing its direction and patterns. Most of the time we have little control of the changes – we enter the room, the smoke swirls because of our mere presence.
Like rationalists are even inclined to, the God Learners made the leap from conceptualizing how this all works together into the hubristic belief that they could control everything and reshape reality according to their will and intellect.
That second paragraph is the key to many mysteries.
Part of the rationalist hubris – is the idea that our data samples are sufficient to create a perfect working model. Not that their basic methodology was wrong. Rather they refused to accept its limits.
