Set in Western Europe during times of war, Eleanor "Ellen" Vertalia, one of the Vanadis of Zhcted, leads the battle into Brune. There are, in fact, seven Vanadis, named for having each received a powerful weapon from the dragon to individually reign over seven territories. The power of the Vanadis invokes dread and fear from their enemies. An earl in the service of the country of Brune, a young archer by the name of Tigre, experienced the Vandis's power firsthand after being defeated on the battlefield by Ellen. However, Ellen chose to spare his life after witnessing his skills, but in exchange, he is asked to serve her.

The Lord Marksman and Michelia novel series is an alternative parallel world to Kawaguchi's Lord Marksman and Vanadis light novel series, with Ludmila instead of Eleonora as the main heroine. In this alternate world, Zhcted does not declare war on Brune, but instead forms an alliance to wage war against the kingdom of Muozinel. A young man named Tigre goes to war in his father's place, and his first taste of battle begins to go well, until Brune's battle lines crumble to an ambush. The commander of Tigre's unit flees, until Ludmila, the Vanadis warrior of Olmutz, comes to the rescue. Two years after that battle, Tigre and Ludmila have a chance reunion, just as the curtain is raised on a new war, and a legendary evil awakens.
