Lately, I've been trying to build up the world, particularly the genealogical history of some of the main characters (it's relevant, since one of the POVs is The Bespectacled King, whose family have only recently risen back to the King's seat with said bespectacled person). This has no been easy, as there aren't many software programs that I've found that make it easy to create a chart following the familial line visually first (Freemind sort of works, but it's not designed to easily follow the lines of sons and marriages, and so on).
And, of course, I've bitten off more than I can chew. Of the four most powerful families in one of the kingdoms of my fantasy world, the first generation of children consists of 20 true blood sons (haven't started on the bastards yet...). No way to keep this all clear without better software (suggestions anyone?).
What about all of you? What adventures are you having exploring other people's worlds, or building your own?
