I make no bones about the fact that Lord Obmi the dwarf is one of my favorite characters in the World of Greyhawk Fantasy Setting. His combination of cunning and ruthlessness, plus his occasional flashes of humor, really appeal to me as qualities of a great villain.
So I present a quick graphic showing his appearances and some of his travels as we know them.
I put Obmi in his room beneath Castle Greyhawk first, as that’s his first chronological appearance in the setting, even if it wasn’t his first published appearance. That comes in Hall of the Fire Giant King, and I place him there as the advisor to King Snurre after returning to his homeland in the Crystalmists.
From there, we know he entered the service of Iuz, both from the sourcebook Iuz the Evil and from the novels Artifact of Evil and Sea of Death. We learn of his missions regarding the Theorparts from those books, and his eventual transfer from the service of Iuz to that of Zuggtmoy (and Iggwilv), to retrieve the third Theorpart. I leave out exact dates, as it will take quite a bit of doing to figure out the dates of the Gord the Rogue books, not to mention the non-canonical status of most of them.
