And, out here in the void between worlds, not far from Pharasma’s Creation—in fact, due to be subsumed into it in only a few more decades of meta-time—there is another world.

It is a moderately large world, as worlds are measured, far smaller than Pharasma's Creation, but more real by some ways of measuring that, and older in meta-time, more ancient and simpler; it might be the seed from which Creation and a thousand worlds like it grew. Many things which are in Golarion, were here first, one of the captains of the Ark among them.

None of this, however, is known or visible to the Ark's passengers as they draw to port. Concepts like 'space' and 'time' have begun to make some sense again, even beyond the Ark's walls and the light of the Gems of Radiance, and this world, seen from the outside, is barely ten thousand miles across, bounded with actual walls of iron and adamant, walls with doors in them, one at each end. It might be an exceptionally large demiplane. (It is in fact larger than the Refuge of Nex, but not by so much that it couldn't possibly have been made by an archmage who wasn't even, technically, a god.)

And the Ark of Erecura enters Arda by the open Gate of Morning—

—and morning comes, for the Radiances which the Ark carries are now the brightest lights that shine upon that darkened world.

Fe-Anar knows this world, from among the worlds that Nefreti Clepati showed him—he is not certain, but 'flat' and 'dark' do a great deal to pinpoint it, and the priors on finding a world of this particular family immediately after departing Pharasma's Creation were not, actually, given that 'tropes' appear to be a feature of his life now, low.

"Something bad has happened here," he tells his fellow captains. "We are likely too late to prevent the worst of it, but things can get much worse, and do, in all worlds that don't get offworld intervention."

He sets the Ark 'down', in an appropriate spot, and the green shimmering energy that had surrounded it vanishes, and it is now simply a part of this Reality.

In the middle of Lake Mithrim there is an island.
