R'lyeh (fictional)

R’lyeh is a fictional city from H.P. Lovecraft’s mythos, described as an ancient, submerged, and mysterious city located beneath the Pacific Ocean. It is known for its bizarre architecture and non-Euclidean geometry, defying conventional physical laws. R’lyeh is the prison and residence of the cosmic entity Cthulhu, who lies dormant beneath the sea, awaiting the right cosmic conditions to rise again. The city symbolizes unknown, inaccessible knowledge and the insignificance of humanity in the face of ancient, powerful forces beyond comprehension. Its presence evokes themes of cosmic horror and the limits of human understanding.
