Fearing capture, he seeks help from his
adoptive mother, Maarva, and his loyal droid, B2EMO, on Ferrix.

Cassian befriends Kino Loy, a floor manager who still blindly believes in the system's promise of eventual release.

teenage daughter to appease corrupt traditionalists.The narrative reaches its emotional climax on Ferrix during Maarva’s funeral.
