Not all communication needs to see the light of day.   A solar creates a cipher to be used by a group of individuals who share a common cause.   The Solar touches the individual and with a flash of his caste sign,initiates the individual into the group.  As long as the Solar commits essence and willpower to the charm, individuals in the group may correspond in the cipher with other group members. Ciphers used by groups bound by supernatural oaths, such as an Eclipse Oath, are unbreakable.

Striking at a block of uncarved stone as if it were a foe upon the
battle-field, the Dragon-Blood carves it into shape. This Charm
can enhance any Craft-based action to build an object, dividing
the time needed to complete each interval in half. If the Dragon-
Blood is assisted by others who knows this Charm, they may
activate it cooperatively. Each cooperative activation increases by
one the factor that the time is divided by, to a maximum dividing
factor of the higher of the crafting Dragon-Blood’s (Essence
or Breeding). For example, if the Dragon-Blood was assisted by
one other character with this Charm, the time needed for each
interval would be divided by three, while with two assisting characters,
it would be divided by four.
