Rigni campaign

The Rigni campaign, codenamed Operation Isomer by Peacekeeper forces, was a military campaign fought between Year 10 to Year 11 on and around the Rigni Sub-Sector in the Zaretian Campaign of the Great War. It was the first major combined offensive by both Aeverian and Luminarian forces against the Zaretian Monarchy.

On Year 10, Peacekeeper forces, arrived in system and landed forces on the star systems of Verdaria, Toolago, Bekkaris and Foorida in the southern sector of the Rigni Sub-Sector, with the objectives of establishing secure supply lines from the areas conquered during Operation Fissure and preventing a potential Zaretian breakout and threatening supply routes. Powerful Aeverian and Luminarian Naval units supported the landings.

The Peacekeepers intended to use the captured systems as bases in supporting a campaign to eventually capture or neutralize the major Monarchy base at Rigni. The Zaretian defenders, who had occupied those systems were outnumbered and overwhelmed by the Peacekeepers, and were quickly suppressed. Not long after, the Peacekeepers mounted a major offensive, engaging multiple systems to secure a route to Rigni.

Surprised by the speed of the Peacekeeper offensive, the Monarchy made several attempts to stop the offensive. Almost every star system the Peacekeepers entered was immediately contested before eventually culminating in the decisive Battle of Rigni in Year 11, with the defeat of the last Monarchy attempt to force Peacekeeper ships out of bombardment range of Rigni and the loss of enough troops to hold Rigni against the Peacekeepers. Remaining Monarchy forces retreated back to Nu-Zartar in the face of a new Peacekeeper offensive.

The Rigni campaign was a significant strategic Peacekeeper combined forces victory in the Zaretian Campaign. While Operation Fissure was a crushing defeat of the Zaretian Monarchy Navy, it did not stop Zaretian offensives, which continued throughout the campaign. The victory at Rigni marked the end for any hopes for the Monarchy to win the Zaretian Campaign and the captured systems would allow Peacekeeper forces to easily assault Nu-Zartar, cumulating in the Battle of Nu-Zartar.
