Create a 1:1 aspect ratio image of a Skald, a joyous viking bard, in full regalia of intricately designed leather armor adorned with Celtic motifs, brandishing a sword and a compact wooden shield with similar patterns. This Skald is captured in a triumphant pose, belting out an inspiring war song amidst a battlefield strewn with fallen warriors. The setting is a realistic, Viking-era fjord with longships anchored in the distance, shrouded in a dense, atmospheric fog. The composition is epic and cinematic, with dynamic volumetric lighting piercing through the mist, and a soft, natural color palette enhancing the ethereal quality of the scene.
