Firiel Dee - The main protagonist, taken care of by Mr. and Mrs. Holy because her father never leaves the tower, the lab in which he and Roux study. She becomes recognized as one of the candidates for the queen's position and finds out her mother was a famed member of the royal family.
Roux (Rumpelsti Ltskin) - Firiel's childhood friend as well as her father's student and assistant. He protects Firiel throughout the series and is obviously enamored by her. In the start of the series, Firiel looks at him more like a little brother, though they later develop a serious relationship.
Adale Roland - A candidate for the queen's position and a princess of the Roland family who becomes one of Firiel's friends.
Gideon Dee (Doctor Dee) - Firiel's father and a scientist and research; Firiel thinks that he cares more about his student (Roux) than her, which is not hard to believe.
Madam Holy - Takes care of Firiel before she lives in the palace with Mr. Holy; she appears throughout the series and helps Firiel.
Mr. Holy - Took care of Firiel with Mrs. Holy.
Eusis Roland - Adale's older brother, he also protects Firiel in the series, and is considered "Roux's rival" by Lot (meaning for the hand of Firiel). He proposes to Firiel which, of course, she rejects.
Count Christbard - Eusis' close friend ("Lot").
Bard - A mysterious minstrel and close guardian to the queen of Gulair with magical powers.
