So it sounds like we're mostly on board for a conversion to Pathfinder, and just deciding what to do world/adventure-wise? WD had a point on Godsmouth Heresy. The game we're in is supposed to start at 1st level, while we're all 7th level (8th if we level up after wrapping this adventure up) here. I kind of assumed we'd have to start partway through Rise of the Runelords, too, due to our level. Honestly, even if the DM on the other game sticks around, it'll be a heck of a long time before we get to the same level. So if we started GH further down the line (assuming there's a point we could merge into), there'd be relatively little risk of overlap. By the time we hit 7th level in the other game, I'm quite certain I'd have forgotten what happened lol. 
Since it looks like Pathfinder is where we're headed regardless of the adventure, I'll just go ahead and ask now: I was thinking of changing Midian's nature's bond to the domain variant. I don't think I've been very good at managing his animal companions, and had been planning to dismiss Garuk when we left the island anyway. With all the lightning Midian's been throwing about, the Weather domain seems like it might be a good thematic fit.
