One of Babylon 5's classic characters was the mysterious Mr. Morden, but one thing I never totally understood was his back-story and then I read this:
Indoctrinated by the Shadows after his capture during an expedition to Z'ha'dum, the Shadows' homeworld, he has accepted to serve because of the Shadows manipulation of his guilt of the death of his wife and child and because they promise to save his family whom he believes are trapped in hyperspace.
I don't remember seeing this part of Morden's back-story in the TV series itself, but it is an awesome twist on a rockin' character.
What exactly happened to Mr. Morden's family and why does he believe that the Shadows can save them?
