Alright, so, here's what I've got on that portal-- or gateway, as the books call it. The short story is that the portal itself is an opening for a god to pass through. It takes a hell of a lot of juice to build up a door like that, which is why we're having trouble with power. And that's worrying enough in itself, but once it's finished draining our power, whatever it is that's created the portal-- or whatever's been summoned by it, depending-- will come through. A god, presumably, or something with god-like power. I guess there's also the possibility that a deity will
leave through the portal, but that might not actually be a better case scenario, depending on what it might take along with it and what it would leave behind.
So what we're looking at, probably, is an enormous ecological shift, in terms of the magical properties of the land and its populations. The kind that they often name historic 'ages' after, like the Stone Age, Bronze Age, and Iron Age (or to use examples from this particular world, the Fire Age, the Exalted Age, and the Blessed Age). I don't know about you all, but if this is what they call the 'Blessed' Age, then I'm not sure I like where this is going.
On a related note, does anyone know anything about a person named Don or where I might find him/her?
