These things, too, we experienced together during our initial descent into the darkness: The air became cooler but also damp, and with the drop in temperature came a kind of gentle sweetness, as of a muted nectar. We also both saw the tiny hand-shaped creatures that lived among the words. The ceilings were higher than we would have guessed, and by the light of our helmets as we looked up, the surveyor could see glints and whorls as of the trails of snails or slugs. Little tufts of moss or lichen dotted that ceiling, and, exhibiting great tensile strength, tiny long-limbed translucent creatures that resembled cave shrimp stilt-walked there as well.
Things only I could see: That the walls minutely rose and fell with the tower’s breathing. That the colors of the words shifted in a rippling effect, like the strobing of a squid. That, with a variation of about three inches above the current words and three inches below, there existed a ghosting of prior words, written in the same cursive script. Effectively, these layers of words formed a watermark, for they were just an impression against the wall, a pale hint of green or sometimes purple the only sign that once they might have been raised letters. Most seemed to repeat the main thread, but some did not.
For a time, while the surveyor took photographic samples of the living words, I read the phantom words to see how they might deviate. It was hard to read them—there were several overlapping strands that started and stopped and started up again. I easily lost track of individual words and phrases. The number of such ghost scripts faded into the wall suggested this process had been ongoing for a long time. Although without some sense of the length of each “cycle,” I could not give even a rough estimate in years.
There was another element to the communications on the wall, too. One I wasn’t sure if the surveyor could see or not. I decided to test her.
“Do you recognize this?” I asked the surveyor, pointing to a kind of interlocking latticework that at first I hadn’t even realized was a pattern but that covered the wall from just below the phantom scripts to just above them, the main strand roughly in the middle. It vaguely resembled scorpions strung end-to-end arising, only to be subsumed again. I didn’t even know if I was looking at a language, per se. It could have been a decorative pattern for all I knew.
Much to my relief, she could see it. “No, I don’t recognize it,” she said. “But I’m not an expert.”
I felt a surge of irritation, but it wasn’t directed at her. I had the wrong brain for this task, and so did she; we needed a linguist. We could look at that latticework script for ages and the most original thought I would have is that it resembled the sharp branching of hard coral. To the surveyor it might resemble the rough tributaries of a vast river.
Eventually, though, I was able to reconstruct fragments of a handful of some of the variants: Why should I rest when wickedness exists in the world … God’s love shines on anyone who understands the limits of endurance, and allows forgiveness … Chosen for the service of a higher power. If the main thread formed a kind of dark, incomprehensible sermon, then the fragments shared an affinity with that purpose without the heightened syntax.
Did they come from longer accounts of some sort, possibly from members of prior expeditions? If so, for what purpose? And over how many years?
But all such questions would be for later, in the light of the surface. Mechanically, like a golem, I just took photographs of key phrases—even as the surveyor thought I was clicking pictures of blank wall, or off-center shots of the main fungal words—to put some distance between myself and whatever I might think about these variants. While the main scrawl continued, and continued to unnerve:… in the black water with the sun shining at midnight, those fruit shall come ripe and in the darkness of that which is golden shall split open to reveal the revelation of the fatal softness in the earth …
Those words defeated me somehow. I took samples as we went, but halfheartedly. All of these tiny remnants I was stuffing into glass tubes with tweezers … what would they tell me? Not much, I felt. Sometimes you get a sense of when the truth of things will not be revealed by microscopes. Soon, too, the sound of the heartbeat through the walls became so loud to me I stopped to put in earplugs to muffle its beat, choosing a moment while the surveyor’s attention lay elsewhere. Be-masked, half-deaf for different reasons, we continued our descent.

It should have been me who noticed the change, not her. But after an hour of downward progress, the surveyor stopped on the steps below me.
“Do you think the words on the wall are becoming … fresher?”
