Myth plays an important part in shaping the reality of Glorantha. Understanding the myths of your culture allow you to practice magic related to these myths. This isn't just magic in the sense that you can produce "magic spells" or enchant objects. Everyone in the world practices magic in order to fit into natural processes of the world and turn them to survival and civilization. Key concepts that exist in the design of this world may be challenging to understand initially, but having a general grasp of these ideas can illuminate the otherwise dry facts that make up the invented histories and cultures of Glorantha.
