Members of the Order
In The Hexer movie and TV series, Falwick, who, unlike the books, is the entire Order's leader, is a spy for Nilfgaard whose assignment after Queen Calanthe's death was to locate Ciri and bring her to Emhyr var Emreis, the Imperator of Nilfgaard. The Order also hired Renfri to kill the priestesses and burn the temple of Melitele in Ellander.
In The Witcher computer game
After Temeria's second war with Nilfgaard, the Order of the Flaming Rose was established by a charismatic leader, Jacques de Aldersberg, on the foundations of the deteriorating Order of the White Rose. His aim was to protect the people from monsters and other evils, as well as to promote the belief in the Eternal Fire.
