An "Elemental Deity" refers to a divine being associated with one of the natural elements: earth, water, fire, or air. These deities are often found in various mythologies and religions, where they embody the characteristics and powers of their respective elements. For example, a fire deity may represent destruction and transformation, while a water deity might symbolize life and purification. In many cultures, elemental deities play a crucial role in creation myths and rituals. They are often invoked for protection, guidance, or to ensure harmony with nature. Examples include Gaia for earth, Poseidon for water, Hephaestus for fire, and Aeolus for air.
