Van'er is observant, smart and loyal man.
Van'er lost his brother during Months of Demons two years before Roland's arrival. Before joining Militia's ranks he had worked in mines.
Inspired by Prince Roland's speech and salary of 10 silver royals per month, Van'er signed up for Militia, believing he would be assigned auxiliary service.
However he soon realized that Militia would be the main force responsible for wall's protection. Disturbed by the lack of personnel and mercenaries, he shared his concerns with Roland when the latter was inspecting training. For his initiative he was appointed as commander of Spear squad.
When Militia was offered to join either Flintlock Squad or Artillery Squad, Van'er eventually decided to chose the latter due to cannon's greater firepower and artillerist's salary being 5 silver royals higher. Since Van'er was a vice-captain he was appointed as artillery captain. There were four artillery teams in total, in his team were Jop, Cat's Claw, Nelson, and Rodney.
Initially they trained with one cannon to prepare it to shoot, from cannon cart detachment to gunpowder loading, without actual firing. Additionally they trained to set cannon onboard of Littletown. After the week of training artillery teams were allowed to shoot cannon balls at turns with angle changing.
