Sometime before the destruction of Starkiller base, the Eclipse was captured by the First Order in a massive fleet action, after the Moff Council onboard was eliminated. During the ship's time in hiding, a surprise came when a ship randomly exited Hyperspace near the Eclipse III, carrying Grand Admiral Rae Sloane, Commandant Hux and Hux's son the three promptly joined the Eclipse's crew. Despite years of failed attempts, the New Republic never managed to collect a helpful amount of data, due to the Moff Council's uncompromisingly jealous guardianship over the pride of the fleet. This resulted in the New Republic not being made aware of her existence until the Remnant's fleet engaged a Republic fleet and completely destroyed it, with only a single transmission making it through the communications network to let them know that a new superweapon had been built. She instantly became the flagship of the Imperial Remnant fleet, as well as the mobile base of operations for the surviving Grand Moffs consequently, she was jealously guarded and kept far away from action. The Super Star Dreadnought was not completed until 21 ABY, when she was christened and launched from an orbital spacedock carved out of a small moon. With the combined manpower and the vast amount of resources required, construction on the Eclipse III finally began.

Negotiations were held with this civilization, and after enough intimidation, they agreed to join the Remnant. As fate would have it, a previously unknown system was found less than a year later, when the Imperial Remnant stumbled across a nearby star system inhabited by comprised of direct descendants of exiles who fled the Sith Empire thousands of years prior. This sytem was found in 14 ABY, with several planets that were perfect for mining the necessary resources, but then the issue of a labor force large enough to complete such a massive undertaking arose. Her keel was originally meant to be laid in the Kuat Drive Yards, but circumstances and recent attacks made it abundantly clear that this would be too risky, and construction was delayed until a viable system outside the reach of the New Republic could be found. It wasn't until after the destruction of her two preceding namesakes, as well as the Emperor himself (clone) that the schematics were finally utilized. However, these schematics were kept secret by the Council of Moffs for fear of spies discovering their existence.

History: The Eclipse III began its life as mere schematics that were drawn by Darth Sidious' clone around 7 ABY, who desired to make the third Eclipse to be even larger and more powerful than her two sister ships.
