The terrible thing, the thought I cannot dislodge after all I have seen, is that I can no longer say with conviction that this is a bad thing. Not when looking at the pristine nature of Area X and then the world beyond, which we have altered so much. Before she died, the psychologist said I had changed, and I think she meant I had changed sides. It isn’t true—I don’t even know if there are sides, or what that might mean—but it could be true. I see now that I could be persuaded. A religious or superstitious person, someone who believed in angels or in demons, might see it differently. Almost anyone else might see it differently. But I am not those people. I am just the biologist; I don’t require any of this to have a deeper meaning.
I am aware that all of this speculation is incomplete, inexact, inaccurate, useless. If I don’t have real answers, it is because we still don’t know what questions to ask. Our instruments are useless, our methodology broken, our motivations selfish.

There is nothing much left to tell you, though I haven’t quite told it right. But I am done trying anyway. After I left the Tower, I returned to base camp briefly, and then I came here, to the top of the lighthouse. I have spent four long days perfecting this account you are reading, for all its faults, and it is supplemented by a second journal that records all of my findings from the various samples taken by myself and other members of the expedition. I have even written a note for my parents.
I have bound these materials together with my husband’s journal and will leave them here, atop the pile beneath the trapdoor. The table and the rug have been moved so that anyone can find what once was hidden. I also have replaced the lighthouse keeper’s photograph in its frame and put it back on the wall of the landing. I have added a second circle around his face because I could not help myself.
If the hints in the journals are accurate, then when the Crawler reaches the end of its latest cycle within the Tower, Area X will enter a convulsive season of barricades and blood, a kind of cataclysmic molting, if you want to think of it that way. Perhaps even sparked by the spread of activated spores erupting from the words written by the Crawler. The past two nights, I have seen a growing cone of energy rising above the Tower and spilling out into the surrounding wilderness. Although nothing has yet come out of the sea, from the ruined village figures have emerged and headed for the Tower. From base camp, no sign of life. From the beach below, there is not even a boot left of the psychologist, as if she has melted into the sand. Every night, the moaning creature has let me know that it retains dominion over its kingdom of reeds.
Observing all of this has quelled the last ashes of the burning compulsion I had to know everything … anything … and in its place remains the knowledge that the brightness is not done with me. It is just beginning, and the thought of continually doing harm to myself to remain human seems somehow pathetic. I will not be here when the thirteenth expedition reaches base camp. (Have they seen me yet, or are they about to? Will I melt into this landscape, or look up from a stand of reeds or the waters of the canal to see some other explorer staring down in disbelief? Will I be aware that anything is wrong or out of place?)
I plan to continue on into Area X, to go as far as I can before it is too late. I will follow my husband up the coast, up past the island, even. I don’t believe I’ll find him—I don’t need to find him—but I want to see what he saw. I want to feel him close, as if he is in the room. And, if I’m honest, I can’t shake the sense that he is still here, somewhere, even if utterly transformed—in the eye of a dolphin, in the touch of an uprising of moss, anywhere and everywhere. Perhaps I’ll even find a boat abandoned on a deserted beach, if I’m lucky, and some sign of what happened next. I could be content with just that, even knowing what I know.
This part I will do alone, leaving you behind. Don’t follow. I’m well beyond you now, and traveling very fast.
Has there always been someone like me to bury the bodies, to have regrets, to carry on after everyone else was dead?
I am the last casualty of both the eleventh and the twelfth expeditions.
I am not returning home.
