Of course. Right now, we're simply moving through an introduction, both to our characters and the overall plot. Once this is finished, there'll be a lot more room for everyone to maneuver freely, including missions, bounties, free exploration, trips to town, and anything else we can think of. And, of course, not everyone has to go on the same mission, so it would be entirely feasible for people to split up into several stories for a time. In all likelihood, the guild will only really come together for major plot events, with a bit of time between them.
