Idh-yaa (Art by Jason Engle)
Idh-yaa, also known as Quum-yaa, Cthulhu's Mate, The Mighty Mother or the Xothic Matriarch, is one of the Ogdru Hem and the mate of Cthulhu.
Description[]
According to the Ponape Scripture, Idh-yaa is a colossal, pale, worm-like monstrosity which dwells beneath the surface of a planet in the green binary Xoth star system.
Overview[]
Idh-yaa resided within the green binary star Xoth. She is not only Cthulhu's mate but also his half-sister, birthing four offspring to him, the "sons" being Ghatanothoa, Ythogtha and Zoth-Ommog, and a single "daughter," Cthylla. When Cthulhu and his spawn travelled to Earth, Idh-yaa apparently stayed behind on her homeworld. Her fate is unknown though she more than likely perished as implied by Lucifer.
