A personal friend of Lord British, a philosopher himself as well. Lord Blackthorn is the man behind the ideas of anarchy and the founder of Chaos Guard. He thinks highly of personal freedom and lack of governmental control.
Greed and denial from the throne after Lord British's ascension drove Blackthorn to hands of Exodus. With promise of power and the crown of Britannia, the being Exodus convinced Blackthorn to ally with him. The alliance altered Blackthorn more than his mind, Exodus altered Blackthorn's body and made him "the ultimate human being". Together they are determined to bring new order to Britannia.
