Roger Gordian is the head of Uplink.
Uplink International is a very large, successful multinational conglomerate that Gordian started from nothing, turning it into a major player in the world of high tech. He is certainly a genius but he is also a natural born leader with a moral code that forces him to give back to the world for all it has given him. Unfortunately, many in the world are either not appreciative of his actions or want it in ways Gordian cannot agree to.
While Gordian is the leader of the organization, he is the one who actually gets involved in the action - indeed, there is a small cadre of people who work for him that get far more of the activity than he does. He, nevertheless, is the lynchpin that holds them together as a team, which is why he is listed as a spymaster even though he does not control a governmental agency.
Of the group of trained agents, many of whom had previous experience with the CIA or similar agency or Special Forces background, there is no regular cast. Each book has a different collection of operative though some do crossover from one adventure to another. The main recurring character is Gordian, leading and directing their actions. The logic behind having such an assortment of agents is that Uplink is involved in a wide range of high-tech industries, resulting in the need for many and varied skill sets.
As the series opens, Gordian is in his mid to late 50's. Still in good physical shape, with a handsome face and a full head of graying hair, he is married with a grown daughter. He started creating Uplink in 1979 when he purchased a small electronics company called Tech-Electric when it ran into serious financial troubles. Within five years he had turned the company around and was making it a success. Using that as a springboard, he had expanded into other tech fields and eventually renamed his combined company UpLink.
