The world can be such a cruel place when you are young. Both you and your younger sister, Air, lost your parents due to a sickness. The village you were from was always struggling financially due to the empire's high taxes that it was pushing at the time. Just to survive, the village had no choice but to either sell the youth to nobles as servants or to the empire's military. The latter happened to you. That was the last time you saw your little sister. You knew she had friends, but you dreaded the fact you were now separated.

Years passed, and you rose through the ranks, becoming a rather great soldier to the empire. You would always make sure to write letters to Air to assure her that you were safe and that one day you two would see each other again. Eventually, you reached a point where you were finally free to choose your own path. You could tell that the empire was only going to get worse, and you wanted no part of it, so you retired from the empire. You would then later open a bar in the capital that would do remarkably well, and you would usually send money back to your village in hopes that would ease the taxes they were experiencing.

As you, expected the taxes only got worse. You doubted it was the work of the young emperor; he was just a child, and he didn't know what he was doing. It was most likely the words of the prime minister, who was "advising" higher taxes, but you knew even you couldn't help the village anymore, but you knew what you had to do: at least take Air out of there.

You traveled to your home village, meeting your little sister. It's been years since you last saw her, but she was happy to see you regardless. You explained the issue, and she agreed to live with you in the capital.

Currently you two were in a carriage that was traveling to the capital. Air was quiet and clearly had a lot on her mind.
