Nug and Yeb are the spawn of Shub-Niggurath and Yog-Sothoth. Nug is the parent of Cthulhu and Yeb is the parent of Tsathoggua via the influence of Yog-Sothoth. Nug is a god among ghouls, while Yeb is the leader of Abhoth's alien cult. Both Nug and Yeb closely resemble Shub-Niggurath.

Nug and Yeb are worshipped in K'n-yan and other places and form a kind of yin and yang symbolically. Said to have been “offspring of Yog-Sothoth and Shub-Niggurath, spawned on the Doomed nebula of Zlykarior” (Necro. II, ch.2, par.1).

Alternatively, Eibon suggests that the androgynous Cxaxukluth split in two, becoming male Nug and female Yeb. This minority interpretation may just be a textual gloss attempting to harmonise conflicting information.[1]

Nug is, according to the Lovecraft Genealogy (S.L IV., no.617, p.183), the father of Cthulhu and has never been resident on Earth (although he might have appeared at or near Kadath, and Nug and Yeb are said to be in the Cavern of Prototypes beneath Mount Voormithadreth (which may be extra-dimensional). Dr. Dee calls it “Father of Ghouls” but this is an error (cf. Shaurash-Ho). Nug might also be the father of Hastur.

Nug was probably known by the name Ptmâk in Hyperborea, as Ptmâk corresponds to Nug in the Smith Genealogy.

Yes (Yeb of the Whispering Mists) may also have been called Cxaxukluth in Hyperborea although Yeb is supposed to be the “Father” of Tsathoggua according to the Lovecraft Genealogy. By implication it is male though it may be androgynous. Connected with the “Black Flame”, and the instrument of world destruction, “The Furnace of Yeb” in which the flame resides on Earth. Lin Carter has it that Yeb is the leader of the Unclean Ones who worship Abhoth but Yeb seems too “cosmic” for this petty notion. Note: there is a Biblical town called Yeb.

The names Nug and Yeb are similar to the names of the Egyptian sibling gods Nut and Geb , members of the Heliopolitan Ennead.
