This is Cthulu perfume. It it real and can be purchased here. This is the description of the scent -- try to keep your skull from exploding out the back of your head:
A creeping, wet, slithering scent, dripping with seaweed, oceanic plants and dark, unfathomable waters.
Not impressed? Hope about if I toldf you they also offer scents for The Deep Ones, Miskatonic University, Nyarlathotep, R'lyeh, Shoggoth, Azathoth, The High Priest Not to Be Described, and more? What if I said they had a perfume for Herbert West, the goddamn Re-Animator?
Aftershave, embalming fluid, and splatterings from a panoply of reanimation reagents.
The 5 milliliter samples are $15, and the 10 ml ones are $25. Thank you, Black Phoenix Alchemy Labs -- you're doing a god's work. It's an elder god who wants to gnaw on our souls for all eternity, but it's a god nonetheless.
