"Magnetar....huge star with an enormous magnetic field
Could possibly have an enormous grav well but players would have to navigate manually to avoid the gravity of the massive star.
Could also have true fog of war in the grav well. Meaning only a limited Line of Sight instead of the entire grav well because the star interrupts sensor systems." You pretty much just defined a Pulsar. a pulsar is a small star with an immense gravitational pull, enourmous output of deadly radiation, and extremlely bright.
