Imperatrix Rivkah lived to the grand age of 98; one year longer than the oldest of her known ancestors. But with her passing the Reipublicae Solis had a choice to make; who would be the first official head of state of the republic. (as Rivkah was not actually elected)
In one of the larger deviations from the plan, political factionalism had already begun in the days of the Imperium as a means of politicing favours, and these factions formally linked up to provide support for various Optimates and Imperators. Imperatrix Ha Nu - the leader of the Alien Friendship Association who had been a supporter of both Naomi and Rivkah's Imperiums - was ultimately chosen.
Ha Nu's rise began with her Test - Sirius IV, which she passed with the Imperator's Standard, bringing the former hothouse world to order and seeding life upon the planet, before taking military imperium of the 2nd Fleet. Her keen involvement in the formation of the Terran Alliance, command experience with 2nd Fleet in engagements with pirates and general popularity with the other Imperators, large numbers of the Optimates and the people thanks to her inspirational style meant she was an all around suitable candidate.
Imperatrix Ha Nu was satisfied that the Cabaran situation was now fully resolved, and considered that the key goal of the navy now was to ensure the prosperity of the republic, for which she was a keen advocate of the fast and nimble Corvette as the mobile solution to pirate operations, and favoured moving away from the mixed fleet formations of the Imperium towards long range artillery and carrier focused Battleship core fleets with escorting Corvette screens.
