Worshiped by many of the major cultures in the Pre-Cataclysmic Age (Picts, Atlanteans and Valusians), his worship kept on into the modern age, at least in the city of Opar, a remnant outpost of Atlantis, where its people mentioned Valka in ancient incantations.
About 30,000 B.C, Valka achieved prominence, which lasted at least 12,000 years.
Circa 28,500 BC or before, in the hills of Zalgara, a sorcerer sacrificed seven goats to Yagotha in the name of the Black Beast of Hell with its Thousand Young, in order to make Yagotha turn the key holding the Old Ones away from Earth's plane. Though the sorcerer was killed, the summoning was a success, and an icy horror, Yagotha himself, came to Earth to prepare the planet for the Old Ones, turning Zalgara into a frozen waste. Valka assisted a hero whose name was forgotten into defeating Yagotha and forcing him into retreat. Yagotha then turned the key and closed the Gate upon the Old Ones.
The people of the city of Opar, a remnant outpost of the Empire of Atlantis, possibly worshiped Valka, which was part of an ancient incantation in a ceremony involving human sacrifice. It is unknown if Valka was the Flaming God they worshiped.
- Valka is the name of a town in Latvia. It is unknown if it was the basis for Howard's character.
