I'm wondering if anyone knows of a list of the creatures in the d20 Call of Cthulhu book? Specifically, I'm wondering if it includes the "Natives of Yaddith"/"Nug-Soth" in there.
Here is a complete list of all creatues and gods that appear in Cthulhu D20:
Azathoth
Cthulhu
Hastur The Unspeakable (The King in Yellow)
Nyarlathotep, The Crawling Chaos
Shub-Niggurath, Black Goat of the Woods With a Thousand Young
Yog-Sothoth
Chaugnat Faughn, The Horror from the Hills
Cthugha
Father Dragon and Mother Hydra
Eihort
Glaaki
Ithaqua
Mordiggian, The Charnel God
Nodens The Hunter, Lordof the Great Abyss
Shudde M'ell
Tsathoggua
Yig, The Father of Serpents
Neither of the creatures you asked about are in the book.
As far as creatures go, the book has the "usual suspects" for Call of Cthulhu..
Mi-Go
Shans
Byakhee
Nightgaunts
Flying Polyps
The Great Race of Yith
Hunting Horror
Hound of Tindalos
Tcho-Tcho
Star Vampire
Fire Vampire
Deep Ones
Animated Corpse
Mummy
Cthonian
Loup-Garou
Shoggoth
Shoggoth Lord
Dark Young of Shub-Niggurath
... there might be others, but I am doing this from memory.
Also from memory, it seems you're missing the ghouls, the elder things, rat things and gugs. There's probably a handful more that neither of us are remembering, though.
