Dame Aedith is an Agent of the Forces of Good against the Foul Undead- not constructs, but vampires. No one else seems ever to have seen any trace of vampirism anywhere, including the authors (although Ardsley Wooster and Carson von Mekkhan have a ... disturbing ... exchange on the possibility), but she hasn't let that stop her. She's been traveling with Master Payne's Circus of Adventure for reasons of her own, where her skill with weapons is appreciated both on and off the stage despite a regrettable knife throwing incident.
