"Eli, is there anything I can help with? If not, I'll be with the porters and the boats, and we'll move in when you've found somewhere a little dryer, eh?"
With the porters and anyone else that'll help, drag the raft and and canoes a good distance onto land. We don't know if the river is tidal or anything like that, so secure them (take 20) with rope - in the order of raft, my canoe, other canoes (I don't have unlimited rope). Chat with the various passengers whilst doing so and Diplomacy the porters.
"So, porters - please, tell me your names. I'm paying you by the day, but there's a few gold bonus in it when we get back safe and sound, right? How long have you been in Rivertown, and where was you both before?"
Approach the priest if she is not busy in preparation.
"Forgive me, Alanorwan - I don't know if the convention dictates that I should address you by a more formal name, or honorific? I was wondering if you could tell me - I don't plan on staying for the ritual tomorrow, for we depart for the lost explorers, but I wondered, how long will the ritual take? What does it entail? And I don't mean this disrespectfully in any way, but what are your expectations regarding what it may achieve? I also have a more mundane question regarding the river. Does its height change greatly with the tide?"
