My Parents gave me a day off from
raiding tombs and discovering shrines to go to the beach once when

Now, those who dive the cyclopean stairways to have their picture taken, childlike, in front of the huge submerged battlements of Yonaguni, must feel the ghost of H.P. Lovecraft matching them stroke for stroke, bubble for bubble, as they descend to depths previously described only by him.
Lovecraft's visions of sunken cities imprisoning the Old Ones, made him famous, but in his later writing, he began to turn his dollar-driven Demons into transcendant Gods.
Transcendence is the ultimate Planetary Mystery. Yonaguni
may be the oldest.
