I found myself moving through an infinite space of rust. There was rust and nothing beneath it, suggestions of shapes and origins which retreated into surface detail upon inspection.
Spires grew like blackberry thorns, fractal and deadly, and I needed to look away before they would grow to meet and prick my eyes. I developed a studiously soft focus as I moved, fleeing the preexisting spines of my attention, and doing my best to grow as little evil by my passing as I could. No thoughts occurred to me, and I moved forever.
Then, I was in a glowing network of tunnels, with transparent walls. I noticed that the light in this space was my own, the light of any living thing, travelling forever and diffusing horizontally before reaching me. The structure of the space could be gleaned by the barest of details, and the tunnel floors had a thin layer of mud and dust, but I could not see it as the light never made it there. Exploration seemed to be the only option until I thought to build cairns of mud, which gradually absorbed and erased all of the light in the stratum, growing warm. As darkness rose, I labored on, eventually constructing a column from floor to ceiling, from which I was born.
Then, I was among a recessed forest, formed in the pores of a craggy landscape I could not ascend. Each pit had a roughly circular aperture to a yellow sky, and the white-barked trees clambered the walls, which sloped inward, jettisoning yellow leaves. On the ground below, it was entirely a mossy marsh, save for bald stone in the center. There was no rain - the water came up from below, and the light came from above.
Between these recesses were large circular tunnels, or gates, hewn into the stone by the hands of my forbears. I studied them, and plotted their lives by their labors in my mind, naming them after their patterns and my guesses as to their behavior.
The sunlight is unbearably harsh at all times on the eyes and skin, and even the trees' leaves and lesser branches will sometimes spark alight, falling to the ground and being snuffed out. I sleep in the tunnels, where the sun can't get me.
This is the best place yet, so I do not move on.
