Setting

The Mercy of Gods is set in a distant future where humanity has established itself on the planet Anjiin. While the exact origins of human settlement on Anjiin are shrouded in mystery, the novel takes place at a pivotal moment when this isolated human colony faces invasion and subjugation by an advanced alien empire known as the Carryx.

The story primarily unfolds across two main settings. Initially, we see the human civilization on Anjiin, a world with a unique native ecosystem that has a different biochemical basis from Earth life. This planet serves as the backdrop for the initial Carryx invasion. Following the conquest, the action shifts dramatically to the Carryx homeworld - a massive world-city dominated by imposing ziggurats where captives from numerous conquered species are held.

Within this alien metropolis, much of the narrative focuses on the confined spaces where human captives are forced to live and work. The research facility where Dafyd and his colleagues are assigned becomes a microcosm of the larger conflict, as they navigate survival, resistance, and moral dilemmas under the watchful eyes of their Carryx overlords. This claustrophobic setting contrasts sharply with the vast scale of the interstellar conflict that forms the backdrop of the story, emphasizing the personal struggles of the characters against the enormity of the galactic stage.

Characters

• Dafyd Alkhor: Initially an unassuming research assistant, Dafyd becomes a key figure in the human group's survival under Carryx rule. His unique insights and skills make him invaluable to both his fellow captives and the alien conquerors. By the end of the novel, Dafyd is appointed as the sole human liaison to the Carryx, secretly vowing to find a way to defeat them. His journey from ordinary scientist to reluctant leader and potential savior of humanity forms the core of the story.

• Tonner Freis: The brilliant but arrogant leader of the human research team. Tonner struggles to maintain his authority and sense of purpose in captivity, often focusing on their assigned research project at the expense of recognizing larger dangers. His complex relationships with both Else and Dafyd add depth to the group dynamics.

• Else Annalise Yannin: A senior researcher and Tonner's lover at the start of the novel. Else is revealed to be hosting an alien “swarm” spy entity, adding a layer of intrigue to her character. She develops a romantic relationship with Dafyd before being killed when the Swarm transfers to a new host.

• Jessyn Kaul: A researcher grappling with mental health issues, Jessyn becomes more assertive and violent after leading the counterattack against the Night Drinkers. Her reunion with her twin brother Jellit significantly impacts her character development.

• The Swarm: A microscopic entity sent as a spy by the Carryx's enemies. Capable of inhabiting and controlling human hosts, the Swarm becomes conflicted due to growing emotions and attachment to Dafyd, adding complexity to its mission.

• Tkson-Malkal, the Librarian: The initial Carryx overseer assigned to the human group. Their interactions with the humans provide insight into Carryx society and motivations.

• Ekur-Tkalal: The new Carryx librarian appointed at the end of the novel. Their arrival signals a shift in the humans' situation and sets up future conflicts.
