an enemy of the Outer Ones whom the Mi-Go serve: Actually, they have never knowingly harmed men, but have often been cruelly wronged and spied upon by our species. There is a whole secret cult of evil men (a man of your mystical erudition will understand me when I link them with Hastur and the Yellow Sign) devoted to the purpose of tracking them down and injuring them on behalf of monstrous powers from other dimensions. It is against these aggressors—not against normal humanity—that the drastic precautions of the Outer Ones are directed. — H. P. Lovecraft, "The Whisperer in Darkness" In "Supernatural Horror In Literature" (written 1926–27, revised 1933, published in The Recluse in 1927), when telling about "The Yellow Sign" by Chambers, H. P. Lovecraft wrote: ...after stumbling queerly upon the hellish and forbidden book of horrors the two learn, among other hideous things which no sane mortal should know, that this talisman is indeed the nameless Yellow Sign handed down from the accursed cult of Hastur—from primordial Carcosa, whereof the volume treats... In Chambers' "The Yellow Sign" the only mentioning of Hastur is: "...We spoke of Hastur and of Cassilda..." Judging from these two quotes, it is quite possible that H. P. Lovecraft not only recognized Hastur as one of the mythos gods, but even made him so recalling Chambers' book. Derleth also developed Hastur into a Great Old One, spawn of Yog-Sothoth, the half-brother of Cthulhu, and possibly the Magnum Innominandum. In this incarnation, Hastur has several Avatars: The Feaster from Afar: A black, shriveled, flying monstrosity with tentacles tipped with razor-sharp talons that can pierce a victim's skull and siphon out the brain. The King in Yellow Anders Fager's "Collected Swedish Cults" features a Stockholm-based coterie known as "The Carcosa Foundation" that worships Hastur. Hastur is amorphous, but he is said to appear as a vast, vaguely octopoid being, similar to his half-niece Cthylla. In the mythos, Hastur is presented as having "a strange effect on artists and playwrights". Other appearances Hastur has appeared in other media. In the light novel and anime series Haiyore! Nyaruko-san, which is based on the Cthulhu mythos, one of the main characters, Hastua, is a Japanized version of and direct reference to Hastur. Hastur is the name of a demon in the TV series adaptation of Good Omens, portrayed by Ned Dennehy. Hastur is the name of a hunter
