Varkath was the eldest of the Thaumaturge Trivium, a trio of sorcerers of legend. While delving into an ancient temple where an evil entity lived, the sorcerers became possessed by it. Their corrupted bodies remained trapped underground for eons.
In modern day, the temple had wound up under Queens, New York. It was explored by Doctor Strange and his apprentice Zelma Stanton in search for mystical artifacts. The possessed Thaumaturge Trivium attacked the intruders, but they were eventually killed one by one. Varkath was stabbed by Doctor Strange with the sword of one of the other possessed magicians. With its host bodies destroyed, the entity possessed Doctor Strange. Once Strange defeated this being, the souls of the Thaumaturge Trivium were freed.
