I'm thinking about this idea where a visitor to the Narratorium has to go through a significant series of thresholds to get to the auditorium - just as one would have to hike into the campsite to reach the campfire. As one walks through the forest, glimpses can be found through the trees to orient yourself to where the campfire is. This collage/perspective is at the entrance, starting up the stairs. The "campfire" is not yet visible.
After ascending the stairs, the "campfire" - or light well - is fully visible and a ramp spirals down the side of it. At the bottom is the seating, which is situated in a circular fashion.
