Diamaton

Originally named D-08, Diamaton was developed for deep-space exploration as a probe satellite specialized in monitoring and tracking deep-space environments, according to lead developer Ishmael. During its development process, however, Diamaton was repurposed into a more portable and compact CUB, with a shift in its application toward rapid ground monitoring. Ishmael revealed that the name Diamaton was inspired by a long-lost knitting device.

Even after Diamaton's development was completed, Ishmael gave its system multiple algorithm updates. In the final update, she left a note with just one sentence: "If you spill coffee on a book, it usually seeps through more than a few pages."

"In an opulent, dimly lit room, a box-like rhombic octahedron rested on the missing person's desk, silently flickering a gloomy purple light. I couldn't tell from its material or structure the source of such a glow. His family told me this octahedron was left behind by a pink-haired guest, a woman who arrived and departed in a hurry, though that was many years ago..." —Notes of an investigator from the Golden Age.

"I still remember it... that missing antique. I'm certain I saw its shine in the darkness and the lighting system was functioning as usual. The color of that light reminded me of the auroras I witnessed along the Arctic Route... But both its shape and exterior have already blurred in my mind, probably because of my aging. Now it feels like an anchor, heavy and submerged in the depths of my dreams." —Diary of an elder on Babylonia

"The universe is an octahedron. I saw it." —Last words of a writer with an unknown date of death
