Luxion's Sphere
Aliases: Luxion body · Floating drone
Description
Luxion's sphere is the small floating drone body he uses to accompany Leon. It is mirror-black, hand-sized, equipped with a single red optical sensor and a synthesised voice, and capable of independent flight, surveillance and hacking at close range.
The sphere is not Luxion's whole mind: that lives aboard Arcadia and across whatever Old Humanity infrastructure he can reach. The drone is a deliberate compromise — small enough to fit in Leon's room, sufficient for daily snark, snide threats and field commands.
It is also the visual shorthand the series uses for Leon's secret advantage. Anyone close enough to spot Luxion's sphere at Leon's shoulder has, by definition, just walked into a much larger problem than they thought.
