Lacuna

Lacuna, or Captain Hook, is a Faerie, a pixie or Wee Folk, in the service of Ace. She first appears in Cold Days.

Description
"Karrin Murphy: If Molly has a turkey baster, maybe we could water board him." Like Toot-Toot, Hook leads a group of Wee Folk with orange lights—what Harry Dresden calls piranha pixies.

Unlike the Za-Lord's Guard, she has a thirst for battle. She also despises pizza and prefers to eat healthier food like celery such as is provided by Molly Carpenter. Lacuna claims that Ace owes her for services rendered and that he does not like Dresden.

Captain Hook is almost as tall as Toot-Toot. Dressed all in black with and covered in a fish hook armor, Dresden first nicknames the fairy "Captain Hook". Lacuna carries an actual sword, of which Toot-Toot seems to be quite jealous.

Without her helmet, Lacuna was gorgeous. Her black hair was in a foot-long braid, she had huge black eyes, paper-white skin with deep purple tattoos that shifted, faded and reappeared. Her features were long and lean. Lacuna had an elegant, dangerous beauty.

Cold Days
In Cold Days, Lacuna's group attack Harry Dresden and nearly defeat him using nails until they are frightened away by an illusion of cats cast by Molly Carpenter. Dresden captures her when the hooks on her armor get caught on his jacket, and taken prisoner; she invokes Winter Law making her effectively Dresden's vassal; she is however not cooperative when Dresden interrogates her. Smitten Toot-Toot offers Lacuna a watermelon candy, which she refuses with a sock in his face.
