CLOUDCATS: Inhabitants of Ondrian, moved there by the Others about
8000 BCE because their original sun was about to go nova.

They resemble Terran mountain lions in size and shape, though because
of their preference for cold climates, their fur is thick and white.
They are highly intelligent, although the first colonists thought them
wild animals; they communicate and manipulate objects with a pair of
tentacular Y-shaped "tongues" that retract into cheek pouches when not
in use.

Cloudcats are solitary hunters, living in mountain caves the Others
provided with psionically-operated survival aids; although the closest
world to their native one, Ondrian is enough harsher that, without the
survival aids, cloudcat art and philosophy would have suffered, perhaps
died. Most are involved with one or the other, many with both, and the
tapestries they weave from their shed fur are in great demand
throughout the Empire. Although most cloudcats never leave their home
territory, some do take advantage of their right (granted in return for
the colonists' free use of the equatorial zone) to travel at will on
Imperial ships.

CLOUD-SILK: A soft, light, tough luxury fabric made from a plant that
thrives only on Herbert's World.

CODES, COLOR: (Stories) Generally seen on military uniforms in the
form of collar tabs, the color codes indicate the service's level.
Imperial forces have no collar tabs; Sector-level have white,
Subsector-level have yellow, System-level have orange, and
Planetary-level have red.

(TE Society) These are the ones on the badges, intended to simplify
mutual identification, especially when not in uniform or regalia. No
color band means no Imperial rank (except for brown, which indicates a
local noble; technically, they have no Imperial standing, but are
generally given the courtesy title of "Excellency"
