Odin's Raven is a mystical, semi-realistic bird with sleek, dark feathers that have a subtle iridescent sheen, reflecting hues of deep blue and purple under light. Its eyes glow with an eerie golden light, symbolizing its connection to Odin. The raven's form is elegant yet slightly menacing, with sharp, angular features and a wingspan that suggests both grace and power. The feathers are intricately detailed, with each one appearing slightly weathered, as if the raven has witnessed countless battles and secrets.
