"According to ancient records, the galaxy's earliest starship designers were initially concerned about the many natural phenomena that posed dangers to space travelers. Few questioned the fact that energy shields were necessary to protect ships and passengers from radiation and micrometeoroids, or that only ship-mounted laser weapons would give travelers a better chance of survival against rogue asteroids and destructive space-borne creatures."
