Intro
The Kingdom of Arcelia—a great nation boasting the greatest prosperity on the continent.
King Albert has eight children, making ten members of the royalty in total. Over the matter of the King's successor, the royals have begun to build their respective factions.
Among them, the Second Princess, Celestia Arcelia, was a somewhat unique existence.
A slightly unreliable, clumsy princess who, despite her kind heart and royal pride, was poor at both politics and management. Even her older sister, the First Princess Alicia, thought her succession to the throne was unlikely.
To such a daughter, the King granted a desolate border territory with zero subjects, zero soldiers, and almost no funds—Noctis.
It was a place where anyone else would have normally given up.
However, by her side stood a single personal knight.
A bodyguard, a consultant, and above all, the one person she trusted from the bottom of her heart.
"I-I will show you that I can become a fine lord!"
This is the story of a princess with nothing and the personal knight who becomes her right hand, building a territory from zero.
Before long, the small borderland will become the center of a grand struggle for succession involving all ten royals.
I'll leave the rest to you, Guest. Good luck.
