CHOAM

CHOAM (Combine Honnete Ober Advancer Mercantiles) is one leg of government of the time. This company sells anything & everything, from pundi rice to exotic spice melange. The Emperor & Great Houses control this corporation, having the most important position being in possession of directorships. This brings great wealth to the houses.

Dune: House Atreides

Melange is the financial crux of CHOAM activities. Without this spice, Bene Gesserit Reverend Mothers could not perform feats of observation and human control, Guild Navigators could not see safe pathways across space, and billions of Imperial citizens would die of addictive withdrawal. Any simpleton knows that such dependence upon a single commodity leads to abuse. We are all at risk.
