Azriel will recover but is unable to fly in battle. Kallias and his army join the war camp. Feyre wonders if Tamlin will join, too.

Mor and Feyre reconcile, and Mor explains why a relationship with Azriel is impossible: Mor is bisexual but only romantically attracted to women. Mor’s sexuality is not accepted in the Hewn City, and she fears her family’s reaction. Mor slept with Cassian because she knew Cassian didn’t want a relationship, unlike Azriel; she hasn’t been honest with Azriel because she’s not ready to share her truth more widely. Feyre promises to be there when she is ready.

The allies realize Hybern will attack the human realms first in retaliation against the Archeron sisters. Magically transporting their armies south will leave them exhausted and vulnerable. Rhys declares they will go anyway. Feyre insists they evacuate the human realms because even a single life is worth the expense. Amren bursts in: She has discovered how to defeat the Cauldron.

Amren says the Archeron sisters can accomplish together what Feyre could not do alone: nullifying the Cauldron. The battle will provide cover for their mission.

Feyre helps Rhys evacuate humans from her former human village to the Summer Court.
