Ten Insane Geniuses for Riskail

This is a continuation of the theme I began in the Mad Wizards post, a revised version of which you can find here.  This particular train of thought and conjecture was started off by a quote from Dungeons and Dragons, Volume One: Men & Magic, page 6:
"...the participants can then be allowed to make their first descent into the dungeons beneath the 'huge ruined pile, a vast castle built by generations of mad wizards and insane geniuses.'"

And you can read the rest of this post over at the Riskail Blog where it has been exapnded to Twelve Insane Geniuses and you can find it here.
