Jason Sterling is the leader of one of the twenty doors comprising the Blackdoor Group. His ambition is matched only by his ruthlessness in achieving his own goals. Very little is known about his past.
Sterling has been watching the power of the immortals grow over the last ten years. He is one of the only humans to know of their existence. He knows that their technology is significantly more advanced. He knows that they control a significant portion of the world's money supply. He views it as his mission to bring the immortals down so that they can be controlled... or eliminated.
