In his bestiary’s entry regarding tigers, Leonardo da Vinci describes a bizarre interaction between humans and these mighty beasts:

 "This is a native of Hyrcania; it bears some resemblance to the panther from the various spots on its skin; and it is an animal of terrifying speed. When the hunter finds its cubs he carries them off instantly, after placing mirrors at the spot from which he has taken them, and immediately takes to flight upon a swift horse."

There are two separate sources of gravity competing for control of the city of Hyperboleon. These operate perpendicularly to one another, drawing objects towards two separate grounds whose horizons meet at a right angle.

He noticed the crystal ball on the oracle's table. “I take it that this is what shows us the future?”

"Nah." Her face flashed briefly into view beneath her hood as she lit another cigarette. "You didn't do your homework, did you? Looking in from outside, the crystal ball shows you the past. Looking out from inside, it shows you the future. Here, let me show you how it works.”

In the late 1890s, scientists at the University Beneath Chicago developed the first atomic bomb, a weapon which they referred to as the "Antithalesian device." Despite it being a milestone of human engineering, this research was never approved for surface publication. After proof of concept testing, the results joined scores of other papers in the vaults of Shaver Hall, only to be read again on a need-to-know basis.

The gargoyles of the Red City cannot fly; the wings of fossilized coral that they carry on their backs serve as an ever-present reminder that they were built by humanity to surveil in stillness.

In the year 1968, there were four separate cases of submarines disappearing under mysterious circumstances: the American Scorpion, the Israeli Dakar, the French Minerve, and the Soviet K-129. The last of these events came under scrutiny when, six years later, a United States black project disguised as a manganese mining operation attempted to locate and salvage what was left of the Soviet submarine. This program was known as “Project Azorian,” and was primarily carried out by a single vessel known as The Glomar Explorer.

"My mother taught me that all of the punctuation marks that you miss while typing build up in your fingertips over time." She held up her hands, revealing that the ends of her digits were covered in black splotches. "So, I haven't used any since I was twelve. I’m chock full of them now, periods, commas, parentheses, you name it.”
