Allegra's Dictionary of the Paranormal
Dark One n. [Origin: Czech, also known as vampires] A Moravian Dark One is doomed to spend his liftime cruising the singles' scene in search of the one woman who can redeem his soul. You think dating is hard? Try it when you're nine hundred years old and you've used every pick-up line in the book. Forming a lasting relationship is even more difficult when the woman who makes your heart sing sees dead people and likes to play with demons.
Summoner n. [Origin English] Someone who summons ghosts, poltergeists, and demon lords. Summoners tend to hang around cities like London that are filled with portals to Hell, haunted inns, and other locations dishy vampires might be found lurking. Most Summoners are female, which makes for difficulties when it comes to explaining to the man who haunts your dreams and fills your soul with love why your pet ghosts can be found hovering around even the most romantic of circumstances.
