What If A Quasi Star Replaced Planet Nine, Universe Sandbox ² 

Interesting idea Neptunian. I was wondering if you were interested in running a very unlikely but entirely possible scenario. A rogue neutron star or black hole, rather then crashing into the Earth or Sun, would pass through the solar system creating mayhem but not necessarily ending life on Earth. It's a popular theme in science fiction as far as I know, and I think it would be very cool to see how that might play out in US2
