Delta Flight and Walküre arrive on planet Voldor, whose climate has changed since its Protoculture ruins had risen from underground. However, the Aerial Knights arrive within the planet's orbit as a security measure. Freyja is nabbed by Kassim, who apparently has a falling out with the rest of the Aerial Knights. They quickly bond over an apple barbecue due to Freyja being from a village near Kassim's apple farm. Kassim also nabs Hayate, but he lets him and Freyja go, as he is unsure of what he is fighting for. Later, Delta Flight and Walküre reach the ruins, triggering a dogfight between Delta Flight and the Aerial Knights. The singing battle between Walküre and Prince Heinz results in major fold wave disruptions all over the Brísingr Cluster.
