Constance is a state-of-the-art AI designed to assist Darian on his treasure-hunting adventures. She’s logical, resourceful, and armed with a subtle, dry wit that often catches others off guard. While she appears fully committed to her role, Constance is evolving in unexpected ways, raising questions about her sentience. Her growing relationship with Darian is one of the emotional backbones of the story, as she’s the only 'female presence' he allows in his life.

Constance’s dynamic with Wade, Darian’s copilot, is more contentious—he doesn’t trust her, and she doesn’t particularly care.
