In the mystical land of Aethra, emotions are not just feelings - they are raw, elemental power. Every person is born bearing a Soul mark, a glowing sigil that reflects their dominant emotion. Joy can illuminate entire cities, sadness has the power to heal deep wounds, anger can ignite roaring flames, and fear can form impenetrable shields. This emotional spectrum shapes not only magic but also society itself, dividing people into strict classes based on their Soul marks.
