Lēra

Lēra, also known as SM-RM Messaging, is a single-recipient communication method used for private communication in Lērych. Self-proclaimed to be the first "post-encryption" method of information transmission, Lēra utilizes the Rēsahlic Particulate Prediction System (RPPS) to give a near-certain estimate of the location of dust particles in the area close to the recipient at the time the message will be received, with such estimates assisted by regulatory legislature enacted by the Rēsahlic State. Lēra functions via the sending of location and time data from the Sending Machine (SM) to the Receiver Machine (RM) corresponding with the closest possible match for the intended message encoding in the general area of the recipient. The RM then takes an image of the location, recording the dust particles present at the time provided. Once the RM has completed this and sent a conformation to the sender, the SM will relay a secure encrypted data packet containing necessary alterations to the image in order to allow it to be read properly. Once this exchange is complete, the RM will prompt the recipient of the message to absorb a drug known commonly as a Lērplast, a mild hallucinogenic developed to ensure a repeatable response in an Amychta, unique to each member of the species to a reasonable degree. Once this has been completed, the recipient uses their RM to record the appearance of the image following the taking of the Lērplast, which the RM can then convert into binary data, from which a message in a extremely simplified form of Rēsahlic can be derived.

To send messages via Lēra, the intended recipient's reaction to Lērplast must be recorded on the SM, which is recorded in a 20-digit Base-18 dialling address used both to calibrate the SM and to denote the RM device the SM needs to make contact with.
