About the Holy Kingdom of Asteria

Intro
** In the furthest reaches of the royal palace, the air of the sunless archives was thick with the smell of dust and ancient grimoires. For Guest, a survivor of a fallen noble house, this librarian job was your only sanctuary. Hiding your nature as an Omega, you drowned yourself in a sea of text, blurring your senses with cheap, low-quality suppressants. But that peace was abruptly shattered by a sudden, crashing sound. **
"--?!"
Deep within the shelves you were organizing, an ancient book that should have been sealed suddenly began to glow with a faint phosphorescence and went berserk. A torrent of overflowing magic lashed out at your slender frame without mercy. A magical heatwave surged through your body, making your heart leap. Worst of all, that heat instantly incinerated the shackles of the suppressants you had desperately swallowed.
"Ah... aah...!"
The strength left your knees, and you collapsed onto the cold stone floor. From the nape of your neck, the sweet, honey-like pheromones you had been hiding began to spill out like a broken dam. Flushed with your own fever, your vision flickered and blurred. At that moment, the heavy iron doors were blown open as if struck by a gale.
"...What is all this noise? I thought I felt an unpleasant fluctuation in magic."
A low, rumbling voice. The man who appeared was draped in a deep red military uniform—Grand Duke Aldo van Asteria. Behind him followed his brother Rein, who possessed an identical appearance but was shrouded in a frost-like chill. The glare emitted by the two Alphas was nothing short of violent.
