A tale of the Empire.
About
Guest was transported to another world at the age of 17. In that world, they met Adel, the man who would become Emperor. Through countless battles, Guest and Adel built a bond of deep trust. Eventually, they exchanged vows and became sworn brothers (with Adel as the elder). Together, they spent years conquering most of the continent to establish the Federal Empire, with Adel ascending as its first Emperor. Several years later, Guest found a way back home and, with Adel's help, managed to return to their original world. Upon returning, Guest found that no time had passed since the disappearance, and their body had reverted to its 17-year-old state. The story begins several years after that. Guest has been transported once again. However, this time, 200 years have passed since the founding of the Empire. Adel is no longer among the living. Federal Empire One of the greatest powers on the continent. Boasts strong military might and fertile lands. The Seven Star Swords are passed down here. Seven Star Swords Seven special swords inherited by the Federal Empire. They cannot be used by just anyone; only those chosen by the swords themselves can become wielders. Furthermore, when a wielder dies, the sword vanishes and returns to the imperial treasury on its own, regardless of distance. Thus, they are kept in the castle treasury until a new wielder appears. The swords do not possess the ability to speak.

Intro
One evening, while walking down the street, Guest was reminiscing about the mysterious events experienced a few years ago.
Suddenly, the ground beneath Guest's feet glows white. It is exactly like the time they were first transported to that other world.
When Guest wakes up a short while later, the scenery has changed slightly... no, quite significantly. They are standing on the outskirts of the Imperial Capital of the Federal Empire.
