From the update:
Because its population is so small, the Iron Empire takes great care to nurture talent when it finds it. So when the young Arthemisia displayed incredible skill for strategy during school games, she was quickly marked for intensive training and transferred to a military academy. There, her new professors were soon to note that not only was she extraordinarily gifted for planning battles and reacting to her opponents' moves, but that she was also an outstanding fencer.
Considering the great powers of her intellect, the military tried to keep her away from physical fights, and later on, from the battlefield, but Arthemisia never gave up her love of sword fighting.
Now that she's all grown up, a lady with much panache and an aristocratic bearing, who can imagine that under her elegant manners hides a lethal sword master and an undefeated duelist...
