Along the journey, they join forces with the legion of Seraphims from Drakon and Miryam heading from Cretea.

Archeron, who tells her about his daughters, and Vassa and Lucien also form a friendship. During the journey, Vassa develops a bond with Mr. Lucien leads them to the site of the battle. When Lucien finds her, the queen is already with Feyre's father on her way to Prythian to aid them in the war. Having already uncovered the queens' treachery months before, Feyre's father bargains with Koschei for a temporary release from Vassa's enslavement. Lucien Vanserra volunteers to go on the quest to find her to see if she can help them in the War with Hybern and hopefully break her curse. Her curse causes her to turn into a firebird during the day and return to her human form at night. Elain mentions that the other women have feathers white as snow and they glide across the water while Vassa rages through the skies above the lake. She sees Vassa and other women kept captive by a 'sorcerer' at a lake within the continent, hidden amongst mountains and ancient forests. Through Elain Archeron's new seer abilities Feyre and the rest of her allies learn of Vassa's fate. Demetra later on leaves a note for Rhysand telling him that Vassa is not ill but does not say what has happened to her, and warns him not to trust the other queens. The queens lie saying she is unwell and thus unable to make the journey to attend. Vassa is absent from the meeting between the five remaining mortal queens and Rhysand and his Inner Circle at the Archeron's Estate to negotiate the delivery of the half of the Book of Breathings that the queens have in their possession. They then spread the lie that she had been sick for the past months. He bounded her to a lake in the continent where he keeps other women enslaved as well. Wanting her gone but unable to kill her due to the fact that her successor was far more willful, the queens sold Vassa to a death-lord who cursed and enslaved her with a spell that turned her into a firebird by day, and a woman by night. She didn't notice how envious the other queens, excluding Demetra, had become once they heard of the Cauldron's powers.

Vassa saw through Jurian's lies and warned her fellow queens against allying with Hybern, stating that Jurian's resurrection was a bad sign and they should raise their armies. The King of Hybern sent Jurian to the mortal queens to inform them of the Cauldron and gain them as allies.
