Communication between several lycans packs was easy enough.
At least to those who could observe it from a distance.
If there was anything useful, it was discussed through howling, something most didn't understand but could at least tell was a form of communication.
But added along the fact that it was in a level of sound indiscernible by those who had less than stellar hearing.
However, this also meant that everyone who was a lycan and knew their language would be able to understand the message being spread–not allowing for much privacy.
Sure, there were codes and such for Humans… but lycans were less interested in something like creating a formulaic code.
If anything, they were a bit too lazy for that.
Which was why, there was also another form of communication through the numerous Shamans in each pack and with the Great Shaman of the Blood Moon Pack.
