Goblins

Goblin culture doesn’t have a concept of “Property”. A stick on the ground and a tool in a locked shed are equally up for grabs if a thing needs doing. They’ll casually take and leave things all over their communities, eat from communal pots, and genuinely Do Not Understand why the Core Races are so Angry and prone to Violence all the time.

Consequently Goblins who live near Core communities develop a reputation as “Thieves”, despite not even having a word for that. (The closest word they have is more like “Greedy”, and it means a person who hides things so nobody else can use them, and it’s a surefire fight-starter to call a Goblin that.)
