Elementarium : Xanders and the Seven Crowns of Jupiter (Tome 1)

In the year 4967 of the Elementarium era, upon the planet Aoxun, in the kingdom of Hell-a realm whose origins traced back five centuries to the great schism of the ancient kingdom of Jupiter-a young girl, Princess Katelynn Shearer, lived as she always had. At least, until the day she was summoned by her father, King William Shearer.
He was on the verge of revealing to her the "dark secrets" surrounding the founding of his kingdom, when word reached him of an occurrence that seemed trivial to Katelynn, yet cast the king into a state she had never witnessed before.
Determined to understand, she chose to follow her father to the scene, sensing that this event was somehow bound to the very secrets he had meant to disclose. Along the way, she encountered, in a dream, a mysterious figure who urged her to seek out a certain Alexanders Schroeder. At the same time, she found herself reunited, after many years, with the crown princes of the other realms born of Jupiter's schism.
Having caught fragments of the conversations shared among the seven monarchs, the young heirs began to question the truth behind the founding of their respective kingdoms. Meanwhile, a revolutionary movement arose, denouncing the Crowns of Jupiter as impostors and striving to restore the rightful king to the throne of a united Jupiter.
Thus, our heroes set forth upon a vast and perilous quest in search of the truth.
