In terms of order, I see Brutus as a scout (high survival, high perception, ranged weapon, etc.) so I would love for him to act in that capacity. I am uncertain as to how Mogwai and Drombar are built, or at the very least, their plans, so I don't know if they have similar aspirations. If so, we could do an alternating thing, or I could cede my role someone better suited for it.
However, if we need to go to close quarters, though I have no problem being up front, it would probably make sense for me to be middle, though with no arcane, I might be about as back-line as we have, though I am probably better suited for melee than your typical fighter archer. Watch, I am willing to take whichever watch is necessary. Does anyone need consecutive sleep for spells? Figured that would determine who did what in terms of watch.
Outside of that, I think we head to the inn and wait till morning.
