in the city's military if she will follow orders of its commander, Yuri Gerneaux, but she refuses. Kat then meets a woman who dropped the last letter she received from her deceased boyfriend over the edge of Hekseville. To find it, she travels inside the World Pillar, a gigantic column that supports Hekseville and stretches from the sky to below the clouds. On her way down, her Shifter powers fade, and she is confronted by Raven, but the two are attacked by Nushi, a giant Nevi. Kat wakes to find herself captive in Boutoume, a city beneath the Pillar, where a group of children are living under the protection of their leader Zaza.

Returning to Hekseville, she finds that a whole year has passed due to the temporal distortions experienced in the lower parts of the World Pillar—under constant Nevi attacks, Hekseville has come under martial law and D'nelica has become its mayor. Kat is forced to fight Nushi one last time, before it is destroyed by an enhanced military operative called Yunica. Syd has become part of the military after its absorption of the civilian police forces. Offered a second chance to join the military efforts against the Nevi, Kat again refuses. She is then asked by a scientist to help gather data about the Nevi, but
