Something on your face must have retained the memory of your joy because she didn’t punish you, just got you in dry clothes and fed you, and asked no questions.

Bypassing the route to base camp, you head for the topographical anomaly with the urgency of a ticking clock driving you. The knowledge—never discussed with Whitby—that the longer you stay, the longer you seem to linger, the greater the opportunity for disaster. That alligator eye staring up at you, with more awareness behind its piercing gaze than you remember. Someone off-camera on the second day of the first expedition saying, “I want to go home,” and Lowry, goofing around, so confident, saying, “What do ya mean? This is our home now. We’ve got everything here. Everything we need. Right?”

Nowhere is this sense of urgency more intense than while passing through the swampy forest that lies a mile or two from the border, where the woods meet a dank black-water gutter. The place where you most often saw evidence of bears and heard things rustling in the darkness of the tree cover.

Whitby’s often silent, and when he speaks his questions and concerns do nothing to alleviate the pressure of that gloom, the sense of intent eternal and everlasting that occupies this stretch of land, that predates Area X. The still, standing water, the oppressive blackness of a sky in which the blue peers down through the trees at startling intervals, only to be taken away again, and only ever seeming to come to you from a thousand miles off anyway. Is this the clearing where three men died during the fifth expedition? Does that pond hold the bodies of men and women from the first eighth? Sometimes, immersed in these overlays, Whitby’s pale whispering form is a jolting shock to you, inseparable from these echoes of prior last days.

Eventually, though, you cross into a more optimistic landscape, one in which you can adapt, reconcile past and present into one vision. Here, a wider path separates the continuing dank swamp forest from open ground, allows you a horizon of a few tall pines scattered among the wild grass and palmetto circles. The lean of that forest means that the darkness ends at an angle casting half the trail in a slanted shade.

There are other borders within Area X, other gauntlets, and you have passed through one to get to the topographical anomaly.

Once there, you know immediately the tower isn’t made of stone—and so does Whitby. Does he wish now, his expression unreadable, that you had put him through conditioning, that he’d been given all the training Central could bestow, not your half measures, your shoddy hypnotism?

The tower is breathing. There is no ambiguity about it: The flesh of the circular top of the anomaly rises and falls with the regular rhythm of a person deep in sleep. No one mentioned this aspect in the reports; you aren’t prepared for it, but how easily you acclimate, give yourself up to it, can already imagine descending even as a part of you is floating, ascending to look down on the foolishness of this decision.
