The sunken city of the Great God Cthulhu. A hellishly dark aquatic scent, evocative of fathomless oceanic deeps, the mysteries of madness buried under crushing black waters, and the brooding eternal evil that lies beneath the waves.
To me, R'Lyeh is a very dark, romantic scent. Reminds me of the N. California coast at sunset. I like it but was expecting a little more... Madness.
I was able to get the effect I wanted when I mixed it with Jazz Funeral though. I also mixed it with Incantation and it turns into a very dark, seductive floral.
Overall, when I have the money, I'm stocking up on it.
