There's a lot to choose from when it comes to building your own D&D game, settings, or character, and the tradition continues with the recent materials from the 5e expansion. A big part of D&D lore and gameplay involves the various races that make up the cultures and nations that serve as a backdrop for most adventures. It can mean the rulebooks, of which there are many, supplemental materials that are used as reference materials, or campaign and adventuring guides. An expansion in the Dungeons & Dragons universe can mean a lot of different things.
