On Demons

In Mistress of Malice and Mercy  (the not-quite-complete last book in the Family Lies trilogy) there is a demon called the Drifdan/Chaisan.  I was asked recently where I got my motivation for them.  While, I admit that I honestly do not know where (or do not want to admit where) the demons in the series come from, this one is pretty easy to answer:

See the fangs on that sucker?  Holy crap!  Like the demons in MMM, she's a keltpo.  If it crinkles or rattles or jingles, it's hers.  Heaven forbid it crinkle and be shiny.  That's her mid-yawn, by the way, she's not trying to attack anyone.  Also, the demons are quite vain - Vi uses a mirror to distract them.  Where did that come from?  The klepto kitty who stares at herself in the mirror all the time.  Yes, I serenade her with the Carly Simon song all the time.

So... there you have it.  Inspiration can come from anywhere - even Subway bag stealing, yawning cats.

What's your inspiration?
