Yhoundeh.
Yhoundeh the elk-goddess is the name of the deity worshipped in the waning days of Hyperborea. Yhoundeh's priests also banned Tsathoggua's cult, and her inquisitors punished any heretics. As the Hyperborean civilization drew to a close, Yhoundeh's priests fell out of favor and the people returned to the worship of Tsathoggua. According to the Parchments of Pnom, Yhoundeh is the wife of Nyarlathotep, avatar of the Outer Gods.
