Dwarves make up one of the elder races, so-called because of their longer life-spans. They tend to look down on short-lived races due to their impermanence. Most, but not all dwarves speak dwarven and common. Dwarves once had mighty underground halls but were evicted by an evil creature that invaded their homes, they now live in above ground cities and mountain castles. Dwarves might have a culture wherein profit is the key to honor. I’m not sure.
