Blackthorn Asylum is the eleventh album by dark ambient duo Nox Arcana. The musical theme is described as being "set in an abandoned sanitarium for the criminally insane where the doctors conducted horrible experiments on the inmates."[4] Nox Arcana once again pays homage to H.P. Lovecraft as they did with their second album Necronomicon, stating "We set Blackthorn Asylum in the 1930s and revisit the dark domain of H.P. Lovecraft. The plot builds upon Lovecraft’s short story "From Beyond" and adds some creepy new twists."[5] And, as with almost every other album this band has released, this album conceals a puzzle, along with a storyline that expounds upon Lovecraft's story.[6]
