A majestic Odin perches upon Yggdrasil's gnarled branch, surrounded by swirling mist and radiant golden light. The All-Father's beard flows like a river of wisdom, as his piercing gaze surveys the realms. Glowing runes etch the ancient tree's bark, pulsing with mystical energy. In the background, Valhalla's gleaming halls rise like a shining citadel, its gates aglow with the fires of fate. The scene is set against a deep indigo sky, stars twinkling like diamonds scattered across the veil of the unknown.
