Gremlins are known to live in the engines of airplanes, the spindles of hard drives, and the pipes of boiler rooms. No space within human industry has ever proven hostile enough to prevent their occupation, making them some of the hardiest lifeforms on this planet. Furthermore, they are notoriously difficult to capture, or even to spot; their presence is only ever known in hindsight, evidenced by chewed-through wires, rust-addled screws, and corrupted data.

“The prism divides humanity into its seven wavelengths,” the angel told me. “Mind, body, shadow, voice, echo, identity, and ghost. Step through the glass, and you shall learn which of these you truly are.”

I thought about what it meant for body and ghost to separate, let alone all of these at once. “Won't that kill me?"

“I can’t answer that question for you,” it replied. “Death is a vague, human expression for things we have other words for. Once you’ve arrived on the other side, you’ll be able to decide for yourself whether or not you’re dead.”

1. An astronaut should be able to subsist for one lunar cycle on nothing but canned sunlight. Only the purest variety will prove their readiness: it should be distilled by the solar panels of low-orbit satellites, then carried back to Earth in the talons of doves.

2. An astronaut should be lowered into a pool of raven’s feathers, then meditate in stillness for three days and three nights. During this ordeal, gravity will tempt them to sink to the bottom, but they must be able to resist through force of will.

If the tales of the old north are to be believed, when the gods created the world, they began by murdering a giant. Ymir, as he was known while alive, was disassembled into his most basic components, then used to sculpt the planet. Mountains were carved from his bones, forests were woven from his hair, and oceans were brewed with his sweat. Once this was done, his eyebrows provided just enough thread to sew the boundaries of reality shut. The last of these stitches marked the end of his usefulness, but also, the beginning of time.

“I’m looking to get my nephew something special for his birthday.”

The witch nodded. “So you are. I take it you’ve heard about the arts that I practice?”

“I have. I was wondering if you could make an alligator for him. It’s his favorite animal.”

“Sure, that’s easy enough. I can make just about any animal that you can imagine."

The imported jar is filled to its midpoint with a soft, transparent dust which, according to its label, is a form of “powdered water.” The printed instructions on its reverse are easy to follow:

1. Fill the container to just beneath its lid with liquid water.

2. Insert cork.

3. Shake vigorously for thirty seconds.

It is a difficult matter for squid to survive without access to a body of water. Only one species is known to do so at length: Oneiroteuthis demiurgis, a symbiont otherwise known as the dreamer squid. When found in nature, it bears little resemblance to its ocean-bound cousins. Its gray tentacles remain tightly curled around its mantle at all times, causing it to appear as little more than a labyrinthine mound of wrinkles. It spends the majority of its lifespan in total stillness, dreaming about a surrounding world that it never sees with its own eyes.
