future henchmen had to rhyme with Bigby. This resulted in Zigby the dwarf; Rigby the cleric; Sigby Griggbyson the fighter; Bigby's apprentice, Nigby; and Digby, Mordenkainen's new apprentice who replaced Bigby. Melf: Melf was an elven character created by Gary Gygax's son Luke. Gary Gygax borrowed Melf's name for the spell Melf's acid arrow. Rary: Rary was a wizard created by Brian Blume and played only until he reached the 3rd level, at which point Blume retired him, having reached his objective, which was to be able to call his character "Medium Rary". Gygax borrowed the name for the spells Rary's mnemonic enhancer and Rary's telepathic bond. Otto: Otto, like Bigby, started life as an evil non-player character wizard in the dungeons of Greyhawk. Tenser and Robilar defeated him in combat, and when given a choice of which master to serve, Otto chose to serve Robilar, thereby becoming a character controlled by Robilar's creator, Rob Kuntz. Thereafter, Otto accompanied Robilar on many adventures, including Robilar's destruction of the Temple of Elemental Evil. Gary Gygax borrowed Otto's name for the spell Otto's irresistible dance.

Pooling their resources, Gygax had the Eight construct a stronghold in the middle of an evil land so they would not have to travel far to find adventure. After three years of game time, the result was the Obsidian Citadel, an octagonal castle which housed the Circle of Eight and their armies.Gygax: "The Obsidian Citadel and its Circle of Eight was original to my own campaign. When Mordenkainen was at a level I considered too high for normal adventuring, I used the money he and his associates had amassed to construct the said fortress." After Gygax was ousted from TSR, Carl Sargent and Rik Rose remolded Gygax's old "Circle of Eight" in The City of Greyhawk boxed set into a new plot device. Instead of a
