msasterisk, I revised the timeline. Is it more clear now?
msasterisk, the protostar is not the star. The huge epxlosion of plasma, as you said, is the main sequence star. The plasma whipping around the main star, eventually gets pulled into the core, and stabilizes. As for the supernova, that's not guaranteed and there's only a possibility it 'may' happen. Thank you for you're comment though, it makes me realize that I may need to alter some things with the in-save guide.
My protostar DEstabilized, creating a huge explosion of plasma, and then the entire star (not just the core!) began fusing, ejecting plasma and creating a bright white glow. Then, with no supernova, it suddenly got sucked into a black hole. Um.
Note: Computer may go supernova.
This crashed my TPT but great save though +1
congrats! page 15 in all-time best saves!
