Orange Sabbath

Orange Sabbath refers to the Sunday that the New Supremacy Insurrection converted Saturn into a star.

Background
Towards the end of the Expansion Wars, the NSI was starting to get desperate, especially with the Venusian Stage turning out to be a major loss for NSI forces. As Saturn was essentially a giant fuel source for the NSI, Unigov seized advantage of this in 2388 and established a massive space fleet blockade around the surface, which were ordered to shoot down any NSI ship trying to refuel. Even though dying Unigov leader at the time Irena McKay was strongly against converting Saturn into a star, (largely due to concerns over collateral damage) second-in-command Lonnie Foss officially declared he would go through with it if he thought it was absolutely necessary.

Although Saturn itself was owned by the NSI, about half of the moons orbiting it were claimed by Unigov, and the other half were claimed by independent colonists. Ultimately, Blanch Readan decided that turning Saturn into a star would not only destroy a massive Unigov space fleet, but essentially fry all of their Saturn-orbit colonies. He eventually gave the order for a lone NSI ship to go through with it, and it launched a Mass Conversion Plasma Core into the deep atmosphere of Saturn.

Aftermath
Settled moons of Saturn became super-heated and bathed in radiation. Although this wasn't as lethal as intended, it still landed crippling blows to the terraforming projects on said moons. The NSI then started a "clean-up" operation in which Unigov-settled Saturnian moons would have their terraformer facilities actively disrupted to render the worlds uninhabitable. The creation of a new star spiked the net amount of ambient heat and radiation in The Solar System. This also had the unintended side-effect of drastically decreasing the general attitude of support towards the NSI, as many unaffiliated colonists' lives were lost in Orange Sabbath.
