Kelly's Data Cube

Kelly's Data Cube debuts in *Leviathan Wakes* as a mysterious pocket-sized black matte cube, a plain solid-state data storage device devoid of lights, screens, or holographic interfaces, hinting at covert protomolecule research. Absent or unmentioned in subsequent books, it remains a tantalizing artifact tied to the early unraveling of the solar system's greatest conspiracy, its secrets potentially unlocked only in the shadows of later crises. Across *The Expanse* series, the cube symbolizes the understated tech that ignites interstellar upheaval, evolving from a mere plot device into a foundational relic of humanity's brush with alien apocalypse.
