Echolocation frees dolphins and their ilk from the need for a two-dimensional alphabet. Though humans hear words as waveforms intended to be drawn and read as sequential glyphs, the sounds made by these creatures are vases sculpted upright in time, each experienced as a single, unique object. Meaning lies in the three-dimensional curvature of their forms, rather than in the ordering of symbols.

“I’m telling you, the seismic readings are fairly clear at this point. It’s down there.”

“I mean, I believe you, but how?”

“From what I understand, the outer surface of the inner core is reinforced with hexagonal plates that hold back the sea of molten rock. There’s no external path inside- its body is armored in all directions.”

“Rose soda, huh?”

“Yeah. They have the original kind here, where the bubbles have thorns.”

“Doesn’t that hurt your tongue?”

“A little bit, yeah. And it always tastes a bit like blood as a result. But I love the texture.” 

The professor’s laboratory was centered by a walk-in freezer, where he stored his collection of cube-shaped pseudobrains. Each was formed from a mixture of carbon and silicon nerves, equally sized, and wrinkled with pearlescent grooves. The chamber’s subzero temperatures prevented them from storing thoughts and memories, allowing each experiment to begin tabula rasa.

There are more than two-thousand species of bird present throughout the Great Agarthan Jungle, from the minuscule anteater hummingbird to the greater spherical penguin. Despite the extraordinary diversity present, however, all of their eggs, no matter the parent, are outwardly identical. Each egg is recognizably Agarthan by its signature gömböc curvature, gumdrop size, and transparent shell that reveals nothing but green jelly inside. If appearances are to be believed, there is no embryo within at all- just the same undifferentiated ooze.

The seventeenth chapter of Abstruse Geometry concerns the mathematical problem of snakes swallowing their own tails. Following in the footsteps of a lost treatise by Athanasius Kircher, the tome describes a mysterious knot known as an “ourobohedron,” which is composed entirely of snakes engaged in varying degrees of autophagy. What it lacks in mathematical rigor, it makes up for in curiosity. The figure is described as follows:

The captain’s wrist bore a living tattoo of a compass rose; as the icy waves tossed her vessel about, its ink contorted so that its longest petal would always point north. Its pigment conspired with the iron in her blood to reveal the world’s magnetic winds. It hadn’t yet proven useful on this journey, as the tramontana had been making itself obvious for weeks, yet she knew that it would soon become a necessity.

The human mind takes up fifteen terabytes of space on average, and accommodating the soul requires for an additional twelve to be available. When compressed into a single unit, however, the complete, disembodied self can be expressed as a mere eighteen terabytes: smaller than the sum of its parts, yet no longer separable into individual segments. This conversion of being, popularly known as the Styx Process, can be performed in under twenty-four hours, as long as the deceased’s tombstone features a sufficiently efficient central processor.
