Fringilla Vigo

A Nilfgaardian sorceress of the Lodge, Anna Henrietta’s relative and Geralt’s former lover, freed from Emhyr’s prison to fight the Wild Hunt.

Fringilla Vigo is a Nilfgaardian sorceress skilled in illusion magic, a member of the Lodge of Sorceresses and a relative of Anna Henrietta, the duchess of Toussaint. She always took great care over her appearance, something many Nilfgaardian mages looked down on, and she has a complicated history with both of the women in Geralt’s life. At the Battle of Sodden Hill she fought for Nilfgaard and blinded Yennefer, and years later she spent a winter as Geralt’s lover.

Fringilla Vigo in The Witcher 3
When Emhyr gave the mages of Nilfgaard a simple choice, serve the empire without question or die in prison, Fringilla quietly took a third path and joined the Lodge. She lived in fear of being found out, and by the time of The Witcher 3 she has been. The emperor holds her prisoner for treason, and everyone assumes she is waiting for the executioner.

Her way out comes when Geralt gathers sorceresses to face the Wild Hunt. In Battle Preparations, Yennefer gives him a letter reminding Emhyr that their bargain covers every sorceress willing to join the fight. In Veni Vidi Vigo Geralt swims out at night to the imperial flagship anchored off Undvik, slipping past the fleet’s searchlights and climbing aboard by the anchor. Emhyr reads the letter and frees Fringilla on condition that she helps against the Hunt, and she teleports Geralt back to Kaer Trolde harbour. With her help secured, everything is in place for the trap on Undvik in On Thin Ice.

In the books
In Baptism of Fire, Assire var Anahid recruits Fringilla into the Lodge. At the meeting in Montecalvo, Yennefer recognises her from Sodden, yet the two reach an odd kind of peace, and Fringilla slyly hints at how Yennefer might slip through the castle’s barrier to go after Ciri.

In The Lady of the Lake, she meets Geralt and his company while visiting Toussaint and, on the Lodge’s orders, seduces him to stall his search for Ciri. It works for a while, and she even gives him a magic amulet to replace his lost medallion. Regis sees straight through her. When Geralt finally prepares to leave, she trades the truth about Yennefer, who never betrayed him and has fallen into Vilgefortz’s hands, for the location of the sorcerer’s lair. Geralt gives her a false one, and the Lodge’s raid finds an abandoned castle. Even so, her amulet later helps Geralt beat Vilgefortz at Stygga Castle, and she votes to let Ciri say goodbye to him.
