A hundred April winds disperse her fragrance,
A thousand wet Octobers scour her footprints,
The ruthless years assail the ancient memory of her presence, yet
Where Yidhra walks the hills do not forget.

~ EXP: "Where Yidhra Walks"

This subject contains information from the Expanded Cthulhu Mythos, and not based on H.P. Lovecraft's works directly. This subject contains information from the Mythos Adjacent Works, and while share similar themes and features of the Mythos are not based on his work, or generally considered a part of the Mythos proper. Yidhra is an Outer God who is worshipped as a beautiful, awesome and terrible earth-mother, similar to Shub-Niggurath and might be connected to the Darkness. She has many avatar forms including Yolanda and Madam Yi since her "life-cycle" centres around absorbing other lifeforms and taking from them their evolutionary advantages (in the process she also takes memories). This cycle of "rebirths" makes her immortal. She has telepathic powers which gives her a link to her servitors, and can project illusions. Her servitors are "the Lurkers in the desert," Xothra and Y'hath, and "the Children of Yidhra" (her human cult).


Madam Yi[]

Madam Yi appears as a beautiful human Asian female, dressed in billowing red, white, and black robes. This avatar has a delicate painted face that looks like that of a porcelain doll and possesses long razor-sharp fingernails. China is where this avatar is encountered, where it mates with and kills the young men provided to her by female led and dominated cults. The mating produces monstrous or deformed offspring, most of which are reabsorbed by her.

Yolanda Prentiss[]

A semi-human reptilian creature which casts a glamour to appear as a beautiful, cultured young woman, Yolanda Prentiss ministers to the Yidhra cult located in Milando, Texas. She has the power to fuse humans and animals into new forms, which she employs as her servitors.

At least one iteration of Yolanda Prentiss was destroyed by a human named Wilhelm Kramer at the same time he murdered his family, who were malformed descendants of Yidhra; unfortunately for Kramer, Yidhra immediately sent a duplicate of Yolanda to deal with him.
