Hart shrugged and continued cleaning her weapon. "Don’t know. I’m not a shaman, but I’ve heard that some voyagers encounter a being that blocks the way to the higher planes, some kind of guardian they call the dweller. From the descriptions I’ve heard, it could look like anything, even your Man of Light. The way I figure it, this Man was the dweller—and the dweller, like the tunnel and the totems, is a construct, a way for a mind to wrap itself around the possibilities of magic. All those things are just symbols for a mind structured toward a mystic rather than an hermetic approach."
