Natasha and Oleg agreed to negotiate with the Silvermane Guards and release some low-risk prisoners as a show of good faith. While guarding captured soldiers, Kruzer’s son learned about the hardships and losses suffered in both the Underworld and Upper District, but one young guard defended the Upper District’s privilege as something earned by his ancestors.

Bronya then told a cableway operator that the lockdown would remain in place, leaving her troubled by the thirteen-year abandonment and the worsening fight against the Fragmentum.

• Stelle and March 7th tried to convince Bronya to help them find the Stellaron, and Bronya agreed to cooperate while they were in the Underworld.
