Hey GM's
Could use some help on how to handle communications throughout the Empire. I've used in my game traditional forms of communication (i.e. horseback, porters, messengers, etc), but were wondering if there are different means. Not familiar enough with the background to know if something already exists.
(I was actually planning on stealing ravens from Game of Thrones, but then the HBO series came out and now it doesn't seem at all original.)
Particulary I'm looking for a way for a celestial wizard to communicate with his patron in Altdorf, but would be interested in how people have handled long distance communication for the masses.
Thanks in advance.
