Yag

Yag is the home planet of Yag-kosha and his fellow exiles who came to Earth long before the Hyborian Age. Yag is described as a green planet that circles forever in the outer fringe of the universe, dreaming far poised in the great blue vastness of Space. The planet is ruled by kings, against whom Yag-kosha and others made war before being defeated and outcast.

Yag is also the home planet of Yothga, the vampire plant that fed on the soul of the sorcerer Pelias while he was a prisoner in the dungeons of his rival Tsotha-lanti. Yag was also referred to by Pelias as Yag the Accursed.
