Author : Natalie Oct 18,2025

Arknights presents an intricately detailed world where the lives of its characters weave together to form a complex and engaging story. Although players can recruit and command many Operators in combat, the game also features memorable non-playable characters (NPCs) whose personal histories profoundly impact the overarching plot. Lemuen, also called "Lemuen the Silent," is one such figure from Laterano. Her past, her connections with others, and her role in the narrative all contribute meaningful layers to the game's vast lore.

This in-depth guide explores Lemuen's character, her intricate ties to key figures such as Exusiai and Mostima, and the pivotal part she plays in the complex political and historical backdrop of Laterano.

Lemuen’s Background and Early Life

Name: Lemuen (Sometimes called “Lemuel”)
Gender: Female
Race: Sankta
Affiliation: Formerly of the Pontifica Cohors Lateran, now with the Lateran Curia’s Seventh Tribunal
Origin: Laterano

Lemuen was adopted into Exusiai's family before Exusiai was born, making her Exusiai's adoptive older sister. The two grew up very close, and alongside their friend Mostima, they formed a strong bond during their youth in Laterano. Lemuen, known for her serene and quiet disposition, eventually gained the epithet "Lemuen the Silent."

Upon finishing her studies, Lemuen joined the Pontifica Cohors Lateran with Mostima, serving as a guard and escort for prominent individuals in Laterano. Her reserved but resolute character earned her both respect and a degree of wariness from those around her.
