I believe the plan is the campaign will wrap up upon completion of the Epic Destiny Quests which puts the characters at 30th level.
I know Door Matt is keen for something new like DarkSun or Shadowrun or even Dark Heresy.
I would of course like to understand your question more before more speculation is made. I would also like to see more posts from you in our campaign thread or your character history thread if you can manage the time.
I am still thinking about how I can make this forum more like WoW to facilitate more input from particular players. Miracles can happen.
/that is all.
