Worldview

Most dwarves choose life underground. It is unusual for them to live in a surface settlement unless events force them up.

Living underground for thousands of years has affected the world view of dwarves dramatically. They believe themselves to be the dominant race in the world, the primary force of civilization and culture. This attitude applies even in campaigns where other races are actually predominant. Dwarves who live below ground don't care who controls the land above so long as they are left alone. The surface races may as well be on another plane of existence. Dwarves see little reason to communicate with other races unless an overpowering common cause exists.

This dwarfcentric view is deeply rooted in all dwarves, regardless of where they live, even when among other races. Dwarves in such places may grudgingly admit that humans or elves have achieved some level of civilization and political power, but these are inferior to their own achievements.
