Centauri Systems is less of a single company, but a conglomerate of many different companies spread across various systems and galaxies. The amount of hierarchy and management involved has lead to the overall CEO being a mystery, whose presence is always felt but whose figure is never seen. Tasks are delegated from the unknown CEO to the various COOs in each sector the company has spread to.
Like most megacorporations, their wealth is unimaginable, and it's common for political institutions to be steeped in corruption. The Delta Aquarii nebula, to its credit, has managed to remain secular enough that CS supposedly hasn't needed to meddle. With its HQ in Human Space, and through the open trade laws established by the Accord, Centauri Systems has seen few losses and much gain.
