Kaz Brekker
The cunning leader of the Dregs gang and Inej’s love interest. Kaz is singularly fixated on settling the score with Van Eck, who double-crossed him and kidnapped Inej. Though his plans are repeatedly thwarted, he always has another scheme up his sleeve and is eventually victorious. Serious, lethal, and emotionally tortured, Kaz is difficult for his compatriots to read and often seems to feel nothing but cold anger. He pushes himself to be vulnerable with Inej, however, and is fond of the rest of the gang.
Inej Ghafa
A former Suli acrobat and Kaz’s most trusted confidant among the Dregs. When Inej is kidnapped and held hostage, she must grapple with her greatest fears as she tries to escape and awaits Kaz’s rescue. Strong, meditative, and brave, Inej’s goal is to get the money Van Eck owes the gang and then buy a ship to exact revenge on slavers, like those that stole her from her family as a girl. Though Kaz and Inej’s relationship is complicated by their various traumas, they make strides toward emotional intimacy across the novel.

Wylan’s father, Van Eck, tries to kill him because he can’t read, and Wylan discovers that, contrary to the story his father had told, his mother is alive, held captive in an asylum. Serious and clever, but filled with self-doubt, Wylan comes to recognize his talents, especially once he understands his father’s evil. He eventually gains control of his father’s estate. As he becomes more confident, he is able to express his feelings to Jesper.

Pleasure-seeking and warm, Nina also struggles with addiction. She ends the novel in mourning after Matthias is senselessly killed.

Merchant Councilman, shipping magnate, Alys’s husband, and Kaz’s enemy. In his eagerness to control parem, Van Eck double-crosses Kaz and is relentless in his efforts to capture Kuwei. He’s filled with pride about the impending birth of a new heir who will supplant Wylan, whose disability disgusts Van Eck. Arrogant, moralizing, and hypocritical, Van Eck believes in his own version of justice and gets his well-deserved comeuppance when the other merchants turn on him, jailing him for fraud.
Pekka Rollins
Head of the Dime Lions who teams up with Van Eck and the swindler responsible for the death of Kaz’s brother. Dishonest and self-serving, Pekka Rollins repeatedly bests Kaz.
