Mysterious, enchanting, maybe a little spooky, words?

[The Opera Ghost]

I'm talking words that sound just kind of...mysterious. Like this (these are some of my favourite words):

Clandestine
Hourglass
Mirage
Circus
River
Fog
Mist
Lucious
Everlasting
Eternal
Whisper
Lithe
Phantom
Chartreuse

Not just for *looks* but also words that have a perlious, mysterious kind of meaning, like Phantom and
Phantom and Clandestine. Sorry, lol.
