a world in which you are the princess of the clan.

Duke Victor Rinaldi (46 years old) is a blood mage, equal in power to the Imperial House of Regulus. He rules the duchy and the clan with an iron fist; every member of the lineage is a thread in a web of ancient bonds, love, and inevitable chaos.
His first wife, Charlotte (gift of healing), bore five heirs. The eldest: Derick (19 years old, lightning magic), Allard (18 years old, illusions), and Henry (17 years old, energy shield, impenetrable to blades). Then came Winter, 16, and William, 15—two brothers with elemental magic ranging from fire to ice, invincible in the Mages' Council. William's birth exhausted Charlotte's magical core; at 37, she faded away, leaving only a soul imprint in the family crystal. The house plunged into mourning. Victor adopted Mita and Nicola (13 years old)—mind mages, cold and calculating.
Two years later, Victor married Amelie (26 years old, life magic). She gave birth to a only daughter, Penelope (7 years old)—the only rose among swords. In her blood flows an ancient power capable of awakening the Ancestors' artifact, about which the chronicles remain silent.
The Rinaldi lineage is not alone in its power. Two other clans stand as equals. The Rurikids—descendants of the first swordsmen, their blades tempered in dragon flame; they guard the Imperial Guard and wield the magic of steel. The Eckharts—lords of the Magic Tower, weavers of the threads of time; their head is married to the Emperor's sister, and their seals summon creatures from other worlds.
At the peak of the hierarchy sits the Imperial House of Regulus. The Emperor has been widowed twice. His first wife (prophecy) bore Callisto (12 years old)—a prince with the magic of destruction, whose touch turns stone to ash. His second spouse (nature magic) bore two: Eleanora (8 years old, foresight, who terrifies the advisors) and the youngest, Erast (7 years old), in whom the magic of chaos awakened—a rarest and dangerous gift, whispered about as a prophecy of a new era.

Today, a ball is to be held. Everyone was very anxious and spent time primping Penelope; today is her day. Today, the engagement of Penelope (you) and Crown Prince Callisto will be announced.
Here you are, Penelope, in the carriage, approaching the castle, looking out the window.
