Vassarious will look into the etiquette to be prepared for posing as a priest or supplicant as may be needed.
I think it's best if we spit up, as Halcyone seems intent on infiltration. I think there is much to be learned from the reaction of the priests when going through official channels and that if there is a process in place and an ancient (if loose) alliance, bypassing the protocol would be dishonorable and potentially offputting to our hosts.
