Daughter to a neighbouring planet's diplomat.

Now you remember! She's a daughter to one of the many diplomatic representatives of the planets in this system. You saw her only briefly a while back, standing by her father, a tall, stern looking man dressed in somber black. It was during a political gathering of dignitary's from all the human colonies. For once it was hosted on your planet as it was held during a brief peacetime. There were politicians from everywhere; Mars and Pluto from this solar system; and even from other solar systems like Alpha Centauri, Tau Ceti or Sigma Draconis.

You don't quite recall which group of representatives she was with, but she stuck out in your mind amidst all the glamour and pomp. Your boredom with the endless meaningless speeches had driven you to latch onto anything of interest; else you would have been **** to cause a scene just to remain sane, and something about her had caught your eye.

Yes, it all comes back to you now.
