Mim, the Halfling Barbarian
An outcast by choice, Mim never understood the subtle ways of her brethren and instead embraced the boisterous nature of a particular group of humans. She left home as a teenager, to the relief of her family, and joined these barbarians, earning a place in their circle through killing a wolf by ripping its throat out with her teeth. She turned out to be even more brutish than the rest of the tribe, however, and departed from their company only a few years later, to the relief of her new found family.
Similarly, Mim joined and abandoned groups of criminals off and on for several years, and people spoke of some of her exploits. When introducing herself to the party of adventurers, she’d say, “I’m merciless, marauding, menacing Mim! My enemies call me bitch. But only once.” Anyone who has ever met her thinks she is insane, and many call her Mad Mim.
Mim holds great disdain for those who are humble and meek, but she will still jump to the innocent’s defense, though begrudgingly at best, and chooses her victims with much more discernment than what it appears to someone witnessing her methods. She finds instant camaraderie with those who are loud, drink heavily, and don’t mind getting punched in the face, but she also appreciates those who know what they want and take it, whether by stealth or brute strength.
