Weasel's brother

Weasel had a younger brother who had joined the mercenary profession.

Biography
The younger brother of Weasel joined the mercenary trade to get closer to his brother. Weasel, however, realized this as foolish especially when he was not skilled enough to become one. During one of their mercenary operations, Weasel and his brother were assigned to two different sides of the conflict, with the latter's side eventually losing. Weasel ultimately didn't warn his brother, despite his side being cornered and being slaughtered, which resulted in his brother's death the next day. When Weasel found his brother's corpse, he saw that the lucky pendant had been chewed through, indicating that in his final moments, his brother became extremely hateful of his brother.

Even though Weasel had no direct involvement in his brother's death, rumors ended up circulated that Weasel had killed him, which eventually resulted in Weasel's mom committing suicide, and his father, in anger for Weasel's perceived role in their deaths, getting into a fight that resulted in scars on Weasel's face and his father subject to a wheelchair.
