Thanks for the help, I think the party would definitely benefit from some sort of conflict that ties all their interests together. The current adventure is one based around travel, and the monks want to spread their faiths so I think I might introduce an area where they can preach on the way, and hopefully this will keep them along. Also, seeing that I'm sending them to the Night Trees in the Silver Marches, there will be plenty of opportunities for combat to tie them together.
