Backstory V2

rough and terribly-written outline:

PRELUDE

• billions of years ago, a highly advanced alien civilization terraformed three moons of Ailuro into habitable paradise worlds, ideal for life. They were then seeded with early forms of life (Earthlike life, yes this mysterious civilization is humanity). This happened in millions of star systems all across this galaxy. It is unknown what happened to them, whether they died out, moved on, or ascended to a higher plane of existence. They left behind a Lifeseed (wip name) that would ensure the life evolving on these planets would be similar to Earthlike life. (impossible to be exactly the same, but the same animals would exist but with different like variants)
• By a few million years ago, anrayal had advanced multicellular life, which had spread to Petrichor via panspermia a while while back.
• Gamics evolve on Anrayal, fast forward, have colonized most of the Ailuro system, huge self sufficient colony on Abylla, other moons have some colonies but not so advanced. Have a technology level a few decades higher than modern day fission intercept.

PRE-MODERN

• Detect spacecraft (this belongs to a new alien civ) decelerating from interstellar travel velocities towards their star system, looks like going for a rendezvous with the Ailuro system itself. However, the amount of ionizing radiation the drive is already emitting is huge, calculated that they have three years to prepare before the radiation levels become too extreme and everyone dies. Aliens are here to find the lifeseed (wip name). This is important to them for some reason.
• Millions are moved into underground cities and shielded bunkers on Anrayal and Abylla. A project to destroy the starship in transit is developed.
• A massive laser/cannon is fired at the incoming ship from the surface of Anrayal. The ship is able to withstand the hit, and quickly returns fire with a full xraser/graser broadside. The battery is vaporized, and most of Anrayal scoured clean.
• A secret and final project is initiated, planning to give the starship minimal reaction time to shoot down a atomically-accelerated projectile. However, this would require the starship to be quite close, so close that the Bleaching would have already happened. With no other options, this uh happens idk it's late I'm not doing good writing
• everybody hunkers down in their bunkers and underground cities. Radiation on surface becomes very intense.
• Project Dead Hand begins. A single massive missile (hidden in an asteroid orbiting Ailuro) powered by an atomic burning wall motor (real thing) accelerates to an extremely fast velocity before impacting the starship. With only a few seconds to react, the starship's defenses react at the last moment, but they are too late. The starship is vaporized by a dozen high-yield nuclear warheads. With no containment mechanism for the kugelblitz powering it, the artificial black hole undergoes an instantaneous superdestructive evaporation, casting huge amounts of ionizing radiation in every direction.
• The few survivors on anrayal are cooked by the blast, with the planet heating up a significant amount and the icebergs melting and seas rising blah blah etc cool flooded cities. cerulea has no life so nothing dies but it gets heated up a little.
