Ningauble of the Seven Eyes - art

Fantastic Stories cover "Adept's Gambit". 

Ningauble of the Seven Eyes. Wow, I guess that's what he looks like... was hiding his face and hands and feet in the stories I've read so far, but did freakily reveal his 7 eyes that can extend very very far... they're supposed to glow slightly green and have cat-like pupils. 

On the picture. Nice and freaky, I like it. Thanks/credit for picture (of an old maganize) to Goodman Games and the Lankhmar PDFs I got from that humble bundle last year. This was in the PDF named "DCCL 8 EightCities". 

Trivia from that PDF (note that "The Twain" means Fafhrd and The Gray Mouser): 

Something that was produced though was the game of

Lankhmar, originally released by TSR in 1976 and ushering

in a long-time partnership between Leiber and the “Game

Wizards.” The game of Lankhmar was based on a wargame

of sorts created by Leiber and Fischer and played during the

years of the Great Depression. The original board, a massive

piece of cardboard that showed the terrain and geography of

Nehwon, was long lost along with the rules the two wrote.

When Gygax learned of this game, he expressed a desire to

reproduce it, leaving Leiber and Fischer with the chore of reconstructing the game from memory. These rewritten rules,

penned in longhand, can be found in the Papers Collection.

 As part of the development of the game, Gygax sent Leiber

and Fischer a number of illustrations done by David C.

Sutherland, III, each depicting his take on the characters

in the game. Fischer sent these back to TSR with a number

of corrections, pointing out where Sutherland had veered

away from Fischer’s own personal interpretations of the

characters and cultures of Nehwon. Sadly, these corrections

arrived too late for them to be implemented. The annotated

illustrations are preserved in the Collection, granting an interesting insight into how the Twain’s co-creator envisioned

the duo and the world they inhabited.
