About the Raven: "The heirs to Ravenscourt were among the most respected and wealthiest of England's lords. Then, oppression and violence struck again, and the seventeenth earl was forced to don his forefather's hood and do battle with the usurpers and the unjust... This man is the Raven." From splash page of story.
