Bridge after bridge, each a test of my courage, had zigzagged me slowly across the chasm. Yet as I stood facing the next bridge, I had the uneasy feeling that I had cheated, as if I had strode unchecked through a child’s hopping game. Did my lack of roots in the Kidona culture or my cold iron make me impervious to the challenges of this task? I looked back to Dewara. He perched still and distant at the beginning of the bridge. Suspicion tapped softly on my shoulder, breathed chill down my neck. Did he hope I would succeed, or was I a stalking horse for some incomprehensible plan of his foreign mind? I stood at the lip of the next bridge and doubted all he had ever told me. Nonetheless, I went on.

The next bridge was of mud brick, solid and ancient. The bridge had block walls along each side and towers at the midpoint. It was wide enough for an oxcart to traverse. It did not swing or sway. I should have felt safe crossing it, yet the hair stood up on my head, arms, and neck. Haunted. That was the word that came to me. The bridge spoke of a time when the Kidona had built things that would stand in place for generations. Dim memories of lively towns tried to reach me. I could not believe them. As I walked out onto the bridge, its ruin was revealed to me. Rain and wind had rounded the corners of the mud bricks. Cracks wandered though the walls that edged it. Time had sucked on this structure, softening and dissolving the decorative carvings that had once stood in bas-relief on its balustrades and arches. This mighty work of the Kidona people was dwindling away, one layer of red dust at a time, just as the Kidona people were dwindling away. I felt a sudden awareness of the connection. When this weakening bridge was gone, eaten by wind and rain and time, the Kidona people would also be gone, not just from this world but from my own as well.

The farther I went, the more obvious was the decay. There were gaps in the paving under my feet, and blue distance showed in the holes. I began to encounter thin runners of vine twining along the walls of the bridge. Tiny flowering plants had found homes in the hollows of the disintegrating bricks, their roots prying into the cracks, and their crawling foliage snaked over the Kidona bricks, obscuring them.

I walked on, into a strange dusk. When I looked back, the long afternoon seemed to linger in the distance. The sun’s warm light shone on Dewara’s crouching figure. But the light faded gently around me as I ventured on. Plant life grew thicker on the bridge. Small trees had found places to root, and tussocks of grass grew around them. I began to hear insects and to smell the fragrance of the blossoms. Less and less of the brickwork was visible; the encroaching forest had swallowed it, cloaking it with greenery and taking it over. The walkway beneath me became ropy with vines and crawling creepers. They engulfed the turrets of the bridge and reached out over my head to tangle with one another. The bridge had become a tunnel of greenery. The twilit sky and the depths below me peeked at me from irregular openings in the foliage.

At some point I halted, feeling more than seeing that I had left the Kidona bridge behind. I now stood upon the forest that had enveloped and devoured it. It felt oddly foreign to me, as if I had left the last vestiges of a familiar world behind and now was venturing into a place where I had no right to be. A pervasive sense of wrongness thrummed through me. My body as much as my mind commanded me to turn back. The passage before me radiated hostility. All of those sensations reached me through a sense I had no name for. I saw a lovely woodland path before me in the evening twilight. A cool sweet wind blew, carrying the scent of evening flowers. I could hear birdcalls in the distance.

I lifted my eyes and looked ahead. The dimming light revealed to me a grandfather tree at the end of the tunnel. The gnarled roots snaked out from that cliff’s edge and crossed what remained of the chasm to become the foundation of the path I now walked. Red flowers the size of dinner plates peeped out from the tree’s thick foliage. Butterflies played lazily about the crown of the big-leaved tree, and grass grew thick beneath it. It beckoned me as a place of peace and rest. Yet I regarded the great tree with suspicion. Was this the final guardian Dewara had spoken about? I wondered if the sylvan serenity before me was a trap. Did it lure me to carelessness? Once I trusted myself to the pathway of tangling roots, would it twist and tumble me into the abyss?

I looked more closely at the network of living vines and roots that would be the final link in my trail. Part of a skull, a yellow-brown dome of bone, protruded from the moss and vines. Beyond it, a skinny root snaked in and then out of a shattered leg bone, as if it had sucked the marrow there and gained sustenance from it. The bones were old but I took no comfort from that. Farther along the pathway, I glimpsed the corroded stump of a broken swanneck. I turned and looked back toward Dewara. He was a tiny figure at the end of a green tube. He perched on the edge of the bluff, watching me. I lifted my arm in greeting to him. He lifted his, not in response but to wave me on.
