Kingdom of Cards - Forever will they Reign

There was once a kingdom of four empires,
Diamonds, Keepers of Treasury,
Hearts, Keepers of Law,
Spades, Keepers of Security,
Clovers, Keepers of Food and Peace,
They all ruled together, although different people belonged to different empires, of which their empire had complete rule over them.
Life was good for Ella Taylor, even if she didn't see her brother, a royal servant, much.
Ella Taylor had her two best friends, and a friend that she saw occasionally when going to trade in the market.
Ella Taylor did not know the world could be a bad place, but knew of some dangers, and therefore wanted to be a Knight.
Being a knight would be awfully hard, as she was a woman, and in a time where women wore these huge dresses.
None the less, she wanted to.
Join her journey to become a knight, facing fear, friendship, unwantedness, romance, teaching, leadership, and a twist that turns everything dark.
