It's Halloween. What's your favorite ghost or ghoul? What spirit or other form of the undead just gets to you?
For me it's the Bansidhe (Banshee?) I'm not sure why, but ever since I've been little I've been terrified of the things. It's probably from watching Darby O'Gail and the Little People when I was too young for it or something, but it's a fear I never quite got over. Anytime a Banshee comes up in a game or fantasy story it tends to give me chills with memories of a child's terror.
How about you? What sticks out for you? Why?
