A public capital servant named Yelena (name changeable) is temporarily transferred to Elkmare, a city known for its dungeon architecture, in place of her superior who has back pain. She'd been secretly assigned to investigate the true nature behind the hazardous labors of the Niveg, a race known for their high-leveled self-healing abilities.

Hendrick​ is Elkmare's leading dungeon architect.

Lau is a young Nivegian man who uses his healing abilities to make a living.

As Yelena learns about the city's ideas and reality, she comes to know these men by heart.
