In contrast to the Mauin Villagers, the hired guards Tanod, a level 13 bald swordsman, and Tambai, a level 14 balding spearman, were actually less experienced in wars even when they were already in their early 30s.
They were siblings born in a town, to cleaner parents. They grew up at the bottom of society, but at least they weren't slaves. For that alone, they felt they felt blessed.
The siblings though, as they got exposed to more things in their youths, had seen the stark contrast of the lives of those people with strength compared to people like their own families who passed day to day with a meal or two.
At some point, the two of them decided to find a way to grow strong so they could change their stature.
