Despite the length of a saguaro’s lifespan, there is only one instant during the course of its life in which it is allowed to dream. This happens at a moment of extraordinary synchronicity, when each of its needles is aligned with a particular star in the skies above and below.

“Now, let’s get started.” The professor drew two large ovals on the blackboard. “What’s the first thing that any mathematician learns about division by zero?”

“That it can’t be done,” one student replied.

“That’s right,” she smiled. “And why is that only half true?”

The android awoke with the sort of headache that only androids ever come to know: that anvil-strike reverberation that resounds throughout an orange-hot skull. It brought with it a sense of being molten, a tension between the factory that came before and the scrapyard yet to come. He knew that he’d felt such a thing before, though he couldn’t remember when. He lamented the fact that there were no painkillers available for his kind.

Due to the prohibitive cost of phoenix feathers, only the city’s wealthiest and most esteemed are allowed to return from the dead. Some hide their plumes among the down of their pillows to prevent death from taking them in their sleep, while others wrap them in smoky bouquets, then stockpile them in refrigerated vaults. Even with such wonders available, however, the population at large still sees immortality as impossible, as each quill costs more money than most will ever make in a lifetime.

The fingerprints engraved into the dagger’s hilt are said to have belonged to Brutus himself. Tradition maintains that they were pressed into the bronze at the moment he first stabbed Caesar, and have remained there ever since. It is possible, however, that these whorls of patina predate even his ownership of the blade, though they certainly are his prints; after all, whosoever holds it always finds that its fingerprints match their own.

The human body and its reflection are not the same beneath their skin. 

The image contained within a silvered mirror’s surface seems identical to its observer, but this semblance is usually only a few photons thick. Beneath the opaque barriers of the double’s visible flesh, a candle burns within a cage of transparent ribs, reinforcing the lifelike coloration of the illusion beyond. It is held in place by the long, glass candlestick of the spine, which refracts the firelight into sinuous rays of vital crimson.

The coyote awoke one morning to find that his roadrunner was gone.

He’d disappeared, beyond the asymptotic horizon which outlined their desert, that unreachable boundary between two nowheres. Together, as predator and prey, they’d followed the same highway westward for thousands of miles, always encroaching on that same horizon, yet finding no end to the repetition of sagebrush and sand.
