Geodan Parcels

One of the unexpected pastimes of geodans consists in the exchange of information via physical objects through long distances. All sorts of archaic and new memory devices traveling in standard cargo ships or "fast" couriers through the Lactean Sphere. This allows them to, whenever they want to relax, get in sync with the slow pace of space travel, or routinely checking the state of each one of the parcels if they need to be slightly more active, but always focusing on the slow transfer of information. Data that could have obviously been transmitted otherwise.

Naturally, this constant exchange of unimportant information is a perfect cover for secrets so important that no amount of encryption could adequately protect them.

Is there someone out there, they ask themselves, smarter than us, who could intercept and decode our interstellar communication systems?
