In Hyperborea’s northernmost mountains, there exists a sanctuary where comets come to roost. Here, natural philosophers have been able to observe some of their more avian characteristics up close: their bodies are covered from nucleus to tail in transparent feathers, and their parrot-like faces can be vaguely discerned underneath the icy mists that surrounds them. Their wings are extraordinary in span, yet are never unfurled during their travels through space, as there is no atmosphere against which to propel themselves.

“What I’ve done in life cannot be changed,” I told her, gazing into the fire. “The future is full of possibility, but the men I have killed know no such luxury- the stories of their lives are told and done.”

“You know nothing of fate, then, child.” The priestess rested her chin upon my shoulder, then wrapped her arms about my waist. “The future is immutable, and to one such as me, always visible. But the past? Ah, it is beyond me, for it is still being decided.”

“I’m looking for a love potion.”

“Of course you are.” It was that time of year again, when teenagers came to the mall seeking far more potent things than they could handle. He had a variety of substitutes that he’d sell them, from concentrated moonlight to seahorse hormones, but he never gave them exactly what they asked for. “Prom’s coming up, yes? And there’s someone in particular that you want to go with you?”

“Have you ever experienced the Tetris effect?”

“I’ve heard it mentioned before. What exactly does it mean?”

“It’s what happens when you play Tetris for too long. The game continues in your head after you’ve quit. Blocks keep falling in your peripheral vision, and bursts of inner music prevent you from falling asleep.”

“Oh, I have! But that’s not even close to what I thought it meant.”

An ancient winter was buried in those caves, pressed between layers of geological strata. It was another kind of season from another kind of time, when the snow was luminous and refused to melt. After nine days spent lost in the dull, indigo glow of those tunnels, Thomas was no longer certain if the cold or hunger would kill him first. Almost all of his skin was numb, yet he could feel the outline of his stomach more clearly than ever before.

“Cherries aren’t technically berries, you know.”

“Wait, what?”

“Berries don’t have pits.”

“Well, what about cherries that contain themselves instead of pits?”

The bone trader opened his cloak, revealing to me that there was nothing but a skeleton beneath. Not everything inside was human in nature; his left ribs were parentheses of ivory, and those on the right had been replaced in their entirety by a caribou’s antler. There were copper bones in his legs that had once belonged to machine men, and rosewood vertebrae interspersed throughout his spine.

“Everything that you see here is open to trade, two or more of yours for one of mine.”

It is a difficult matter for ants to dream. The mental processing required takes up the majority of their small bodies, overflowing outward from tangled nerves into the strange oozes that fill their abdomens. Even these, the most social creatures on the planet, sometimes desire to be alone within their own minds.
