Describe your first "Real" campaign as a GM

That is to say, not just a game where you were running a generic dungeon, or one where you were playing out adventures at random without any thought process behind it.

What was the first actual world you ran: was it homebrewed or published? if the former what were its themes and influences? if the latter, where was it located in the setting and what was the basic background to the campaign?

And in either case, what were your motivations for running that particular campaign?
