On a whim, my wife went to the Century system in ME2 - that's the one I mentioned earlier.
Looking at all the planets, she noted that the entire solar system is a wreck. One planet is surrounded by hundreds of moons and the dust from other, shattered moons, all of that probably a result of mass accelerator cannons.
Two planets have no atmosphere, but evidence shows that they did have atmosphere before.
One planet has a gigantic freaking bullethole in it.
There was a battle that tore the entire solar system apart. A fight on that scale beggars the imagination, and I don't use that term lightly - multiple planets were rendered uninhabitable or had enormous chunks blown out of them, forming entirely new celestial bodies. Small planetoids were obliterated altogether.
Whatever happened 37 million years ago is goign to com up again, of course. It's already come up once. I'm just kind of marveling at the suggestion of scale here.
The idea of a fight that could tear apart a solar system is glorious and terrifying in its scale. This universe has some scary shit.
