In the books
Theron is mentioned in The World of Ice and Fire by Maester Yandel. Born Theron Pyke, he is a bastard of the Iron Islands. In his manuscript Strange Stone he postulates the existence of Deep Ones a "queer, misshapen race of half men sired by creatures of the salt seas upon human women". Theron suggested they inspired the legend of merlings and that the sea creatures who fathered them inspired the religion of the Drowned God. He also noted a certain likeness between the black stone of the ancient fortress on Battle Isle that serves as foundation to the Hightower and that of the Seastone Chair, both of unknown origin, and postulated they had been constructed by the Deep Ones
