The body of a sea serpent is most often seen as a sine wave. As it propels itself across the water, its length protrudes from the ocean as a series of archways between the tail and the head. When humans attempt to observe the creature from beneath the water, however, they discover that there’s nothing at all to be seen. For this reason, many have written off the mysterious beast’s existence altogether; despite the profound number of sightings over time, no physical specimen has ever been recovered.

Some say that it was once a second moon. When viewed against the horizon, it’s easy to see why; the mountain is perfectly round when observed from any direction, and widest at its midsection. If positioned just right during dusk or dawn, its presence can cause the illusion of a total eclipse.

Most who tell the story agree about how it started, but not where- some say Fargo, others, Des Moines. On a handful of computers in some high school’s library, clouds of gray and black pixels began flowing across their monitors until nothing else could be seen. Eventually, an overwhelming pressure behind the glass caused it to shatter, allowing clouds of virtual smoke to escape.

Much like the pilot’s seat within a jet fighter, the human heart is capable of ejecting from the body entirely should an emergency arise. When the mechanism is triggered, pressure builds within its chambers until a critical level is reached, at which point the aorta detaches from the rest of the circulatory system and serves as an escape thruster. The entire supply of blood within the body is repurposed towards this launch, causing the heart to exit through the mouth at just under a bullet’s speed.

Only one universe exists (hence, the prefix: “uni”). This axiom holds true in every single universe, regardless of what is said by the inhabitants of others. Those who commute between realities on a regular basis understand this better than anyone else, and use it to their advantage. For these bold wanderers, what exists is understood to be relative, and contingent upon their closeness to the void.

“You’re not going to find anything down there,” Dr. Price explained. “There’s no such thing as a negative radio frequency. You can represent them mathematically, sure, but there’s no real world analogue. A wave observed forward or backward in time is physically identical.”

Those words didn’t seem to have any effect on her student, however, who continued turning the knob on her device counterclockwise. “Well, you and I might know that, but does the radio?”

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.”
