The duties of the Supreme Chancellor are far from limited to the capital of the Galactic Republic, and the importance of the office demands that the chancellor be able to travel at a moment's notice. As such, a vessel is continually maintained for the exclusive use of the Supreme Chancellor.
Today, that ship is the Founder. Unlike many of its predecessors, it was built for an era of war and uncertainty, and bears the hallmarks of a top-class fighting vessel despite its diplomatic duties. Its architects were determined that the Founder not meet the same fate as the previous Supreme Chancellor's vessel‒a beautiful, luxurious and powerful cruiser obliterated during the Sacking of Coruscant.
