I don't know that Ch'dau would "be in favor" of escorting the Lysorans to their shrine, to be honest. He's had enough of this road, for one, and won't relish the thoughts of spending an extra week on it just to "babysit a group of weak, cowardly priests," for another. He'd much prefer spending another hour or so en route to Crandel where he might get out of this weather, find a nice, bloody slab of meat, and a dry place to rest.
Now, if the consensus in the party is that we do escort the pilgrims to their shrine, Ch'dau will begrudginly comply but is likely to be more than a little cranky about it. 
Defenitely gives us some RP fodder to work with in the game thread, though, so, if anyone would like to bring the issue up in game, feel free. I'll be there to put in the kitty's two coppers!
