War against the Sith

The War against the Sith, also known as the Novayan Stellar Commonwealth–Sith Empire War and the Void Coalition–Sith Order War, is a conflict spanning several centuries that began with the incident at Deimos IV, which saw the Sith kidnapping Deimosian children and later truly began with the seven-months siege of Marawat, which saw the most brutal fighting since Void Coalition history.
The conflict extended into other universes and multiverses, such as Multiverse Sierra-Charlie and Universe Alpha-November-India-Mike-Echo, the later of which saw espionage and counter-espionage wars between the Void Coalition and the Sith Order, which ended in the battle of Earth, pitting a Void Coalition armada with the Monarch Fortitude being arrayed against a Sith-Imperial armada, which was defeated. Though almost all Sith groups were eliminated in the universes and multiverses they infiltrated, it wasn't until that the Coalition–First Order War - known as the Jedi Coalition–Sith Order War and Operation Sovereign Justice - saw the complete defeat and annihilation of the Sith and, unintendedly, the exposure of the history of the war against the Sith to Universe ANIME's Earth.
