Golden Sun Sandbox RP? [Contains spoilers for The Lost Age]

And now for something completely different.

How many of you people have played Golden Sun and would like to do a single, semi-long RP based off of it? I don't have a whole lot of stuff in mind (Climbing the Elemental Rocks or Lighthouses would be cool, but take WAY too long and isn't very original), but maybe someone else has an idea for a story we can use.

Personally, I'm fascinated by Garoh, the Werewolf town in The Lost Age. I don't think the source of the curse is explained in the games, which gives us a chance to fill it in for ourselves. My idea was to take a team of four Adepts -one of each element- to discover and undo the cause of the Werewolf Curse. What do you say? Does it sound like a good idea to do this?

If interested, please let me know your elemental preference for an Adept. I have an idea for a Jupiter Adept for this specific scenario, but I could technically work with any element, so.
