In European myth, they are commonly depicted as hoarders of gold and treasure, often confronting heroes. Conversely, in many Asian cultures, dragons are considered benevolent, symbolizing strength, wisdom, and fertility. Their dual representation as both destroyers and guardians reflects the complex nature of humanity's relationship with wealth and power, making dragons significant in the mythological landscapes around the world.
