Once, uncounted eons ago, when wizards were called "magic-users" and adventures were called "modules", there was a dungeon module called B1: In Search of the Unknown. This module describes Quasqueton, the legendary home of Rogann (a mighty warrior) and Zelligar (an equally powerful wizard). This module also happened to come in every box of the D&D Basic Set by J. Eric Holmes (the "blue box" edition, the one before the more famous "red box"). That was the very first D&D set I ever owned.
Thus it was that I learned my first lessons on how to play and run D&D from that set, and (in a way) from the mighty wizard Zeilligar. When it came time to pick a name, it just seemed right to honor my gaming roots in that way.
