A moratorium is in effect on adding information from Fire and Blood until December 20th.
Deep Ones are a species posited by Maester Theron in his manuscript Strange Stone. Theron drew a connection between the black stone of the Seastone Chair and that of the ancient fortress that serves as foundation of the Hightower. Theron suggested they were created by the Deep Ones, a "queer, misshapen race of half men sired by creatures of the salt seas upon human women", according to Maester Yandel. Theron suggests they inspired the legend of merlings and that the sea creatures who fathered them inspired the religion of the Drowned God.
The legends of Lorath claim that the Lorathi mazemakers were destroyed by creatures from the sea, whereas the folk of the Thousand Islands sacrifice sailors to squamous, fish-headed gods, of which stone idols emerge when the tide is low. It is possible these stories and beliefs are related to Theron's Deep Ones.
