Sneaky, Powerful and Evil one.

All powerful and Evil Spook of the Night can be quite terrifying.

If you are lucky enough to meet this queen of Dark then either Run or offer her a big handshake. (It is best to be on the better side of her)

She sticks to the night because there are less do-gooders around and she can twist fates for her own entertainment.
"Oh my gosh! Rowanne is Dead with a harpoon through her neck!"

"Looks like Spook of the Night got to her."
