Lacuna

Lacuna first appears in the Cold Days as a fairy in the service of Ace. She first appears dressed all in black with and covered in a fish hook armor, Harry first nicknames the fairy Captain Hook. She also carries an actual sword, to which Toot-Toot seems to be quite jealous of. Lacuna is later unintentionally captured by Harry by the simple fact that the hooks on her armor got caught on his jacket when he was swatting her away. When she is captured she is put in the oven at Molly's apartment. Before she is questioned Harry calls her a prisoner and that she must answer questions. The pixie attempts an escape but Toot-Toot gives the fairy a smack-down. Just before he is about to kill her, she invokes her sacred rights as a prisoner. Toot-Toot is furious, until he finds out she is a girl when she removes her helm. Harry takes care of his prisoner in exchange for assistance. She reluctantly agrees to help.
