As you may know, Primordia is in a binary system--one with both a red giant and a blue giant star.
One of my favorite shows, How the Universe Works, had a recent episode about the possibility of inhabitable planets in binary systems. It's the second episode of season six, and it's called "Twin Suns, The Alien Mysteries". It's pretty interesting if you're into this kind of thing, or if you're considering using a binary system in your game.
