Kobolds will fit into just about any niche they can. There are about as many "civilized" Kobolds as barbaric Kobolds. They have become much more a part of society than other bestial humanoids. Many of them handle menial labor, such as delivering letters and packages or as helping hands for shopkeepers. They generally don't see the need to aspire to anything greater, because they can live on about half as much money as most other races.
