Hugo was once a knightly prodigy, known far and wide for his fighting skill, but swore off violence for unknown reasons and became the Knights of Favonius' only archivist.

Functioning as the Knights of Favonius' main archivist, Hugo takes his job very seriously. His stern demeanor and imposing appearance intimidates all who enter the archives while he's working. Despite his appearance, he's very happy to help anyone who needs help, often going on the field when the Knights are short staffed. He's very anti-violence and will go to great lengths to avoid being involved in or causing physical fights.

Hugo's job as archivist isn't a light one. He's always on the move; collecting documents, recording the Knights' yearly expences, and writing accounts of every mission the Knights carry out, from collecting things blown away by the wind to the honorary induction of a knight. Every thing that happens in Mondstadt is recorded within the archives by his dilligent hands. Despite all of Hugo's hard work, the only ones who will ever view the archives are his fellow Knights.

Hugo was once one of the Knights of Favonius' greatest knights, charging into battle with a smile on his face at the thought of keeping his city safe. His combat skill and ability to stay calm while fighting made him a fearsome opponent, rising to a high rank within 2 years. One day, he went on an expedition to Dragonspine, and what was once a group of five returned a group of one. No one but him knows what happened that day, but it made him swear off fighting entirely.
