Mythos adjacent Seal Thanaroa is a mysterious evil entity, manifesting as a pillar of dazzling light, dwelling in the ruins of Nan Madol, near Ponape. Its name recalls that of Polynesian creator god Tangaroa.

Behind the MythosEdit

This entity is introduced in Abraham Merritt's fantasy novel "The Moon Pool" (1918) and its sequel "The Conquest of the Moon Pool" (1919) (then collected in 1948 as a whole story on Fantastic Novels magazine, divided in multiple issues), sometimes cited as an influence on "The Call of Cthulhu" by H. P. Lovecraft, which may in turn have itself influenced Merritt's later story "Dwellers in the Mirage".
