Adele, concretely. Specially if you are a demon of deceit or false god and she knows your True Name.
Damn, sometimes it gets even annoying the fact that everything is filtered through Ars when I am by myself... and sometimes when I am NOT alone as well.
Beautiful song. Beautiful spell effect, too. Thanks!
I can access it just fine (it's the audio to Adele's Set Fire to the Rain, with lyrics), but I'm in the USA. It's possible that it may not be available in some other countries for whatever reason.
