Marius Drake has always believed in the ideals of the Federation and has done everything within his power to ensure that the human planets stay unified. Marius knows that a strong Federation is required for humans to remain the dominant race in the known universe, so he must make sweeping changes now that the corrupt Grand Senate is a thing of the past. He also can't ignore the threat of the Outsiders out on the Rim. Lucky for him that he has his protege, Roman Garibaldi, who he can send out to the Rim with the main fleet while he takes care of things on Earth. Of course no plan ever survives first contact with the enemy and the Rim is a very long way from Earth.
