Nanotic Cloud

Nano-tech...nanotic. Cloud--the ultra fine mist that can potentially be seen when the nanites swarm to carry out their programming.
Usually found at nodes, close to serious power sources.
Programming them directly is outside the capacity of mere meat mortals; it is accomplished directly through the AIs. Said mortals can program them mostly through voice interfacing with the AI, but since the Sundering, very few even know what the Cloud actually is.
A classic example of St Clarke's Law:
[q]Any sufficiently advanced technology is indistinguishable from magic.[/q]
so for nearly all sebb , "magic" exists.
