THE ENCYCLOPEDIA GALACTICA
A Rigellian term that loosely translates as 'trusted messenger'. The term dates back to the Warlord period in Rigellian history. Some flavour of that period can be gained from the fact that the Rigellians have the same word for both 'tax collector' and 'bandit'.
More recently the term has cme to be used by interstellar freighters Armstrong Cuthbert for their courier service, although there are legal battles with the Rigellian government over the patenting of the term. These disputes are expected to reach the supreme court for a final judgement some time in the next thousand years.
