No one got this riddle right, want to take a shot at it?

[Miss Lissa]

A virtuoso of this masterpiece.
For I achieve an art.
An illusion of words,
A reminiscence of mirage.
The sound of sorrow,
The sorrow of hope.
A mask of reliance,
Deceit that prevails.
Illumination of the night,
Obscurity of the era.
An abstract property,
Intricate barely describes.

What skill do I master?
No, it's not art, photography, or a painting.
Sin is the closest so far. No one has guessed it though.
Some of you are on the right track. It's a bad thing.

 

[Snidely]

Maybe you hang drapes or sing at night.

Don't give up your day job.
