Guardians of the Word
Colloquially known as the Couriers, the Guardians of the Word is Protester order of paladin couriers & diplomats founded in Autumn of 1414 during the Schism War. They're the only officially recognized Protestor faith. Mostly their Oath, as their name implies, involved being sworn protectors of messages. This was hugely important to ending the Schism Wars, and the Couriers have grown into a powerful order of message carriers.
