A post “end” location on the star map. You can fly there and it’s the only way to gather promethium, a material you need to craft the post game super science. I don’t think the shattered planet is supposed to be reached. It’s insanely far away and the asteroids get bonkers. But that didn’t stop some maniacs to actually do it with a butt load of nukes.
They didn’t give a shit about children getting slaughtered in schools for decades. They won’t start caring now.
