Create a striking fantasy character design featuring a mystical being with prominent horns and ethereal, flowing white hair. The character is enveloped in a vibrant red aura that suggests powerful magic or energy. The background emits a swirling mist of orange and dark tones, enhancing the otherworldly atmosphere. Incorporate intricate details on the character's attire, merging elements of nature and dark magic, to reflect a connection to ancient spells and elemental forces. Aim for a dramatic pose that conveys strength and mystique.
