Leandra Cheviat

Adale's older sister, Leandra is ruthless about obtaining what she wants. She works for the Hermes organization and assumes the identity of "Sister Lain", a professor of Taurus Academy, in order to spy on Roux and try to obtain professor Dee's research. Afterwards, she enters a brief political marriage with Liamon Riez, Queen Astraea's son, to reach her ultimate goal of being the next Star Queen. Although she seems hungry for power, Leandra is also interested in liberating the scientific knowledge that the royal court had kept from the people and branded as heresy.
