Well, we can go into broad ideas on that.
Those of you more capable of academic force study- and although he did not specifically ask, I will include Azarl in that- can indeed learn a bit about the Harmony from Ascar.
However, the major issue is this- Ascar learned it first hand, at first observing an then partaking in some of the Thaloissian joining (not easy, as he points out, for a man to get in on that). It;s something you have to experience to learn.
Therefore, the bonus quest for you guys is- if you can very closely observe the process of the Thalossian Circle- close and long enough to meditate about it and sense it out- you can start to learn of its nature, and its weaknesses.
Other than that- it's time to go. A couple of things to think about. First of all, what are you guys going to pretend to be? You have no idea what yo are going to run into out there, in your dinky little ship, so get an idea down.
Also, you can pick up Con Gordo along the way- Bardock has expressed an interest in rejoining. Presumably he got up to this own business whilst you guys were at the casino but he's available again now, and this will be the last chance to pick up people for a while.
