I volunteered my scratching and markmaking, completing a total of four particularly foul or corrupt outer beings thus far with more on the way. My first two, the Twin Blasphemies Nug and Yeb, come from Lovecraft through a number of stories which harbor no physical description aside from 'they look like their mom, Shub-Niggurath.'
So I consulted the Mythos-corrupted scholar Robert Parker, tended to his recommended reading (I call it 'research' to those who question my time management), listened to Robert Price read aloud Joe Pulver Sr.'s channeling of "The Black Litany of Nug and Yeb," followed the faint scent of Mesoamerican mythology from the stories, and arrived at a mixture of Shubby and physical descriptions of the Black and Red versions of the Azteca god Tezcatlipoca (Black Tezcatlipoca and Xipe Totec, respectively).
Now keep in mind this was my personal path to crafting an image for the two, as the illustrious James Mishler is writing up the full descriptions for the two!
This is what came out:
I also completed The Beast of Unbidden Challenges, based on an excellent description from Nate, the creator of A Desolate Shrine. Here's the cutie:
Following with the mad, lost god Qu'pan, developed by Richard Iorio II, who runs Rogue Games (Colonial Gothic; Shadow, Sword & Spell).
Full stats and descriptions for these godlings can be found in the forthcoming Expanded Petty Gods over at Gorgonmilk. Cheers!
