Create a hyper-detailed, 4K image of a male necromancer in his mid-twenties with long, flowing brown hair and a short beard. He should be wearing simple yet dark, tattered clothes complemented by a traditional Scottish kilt. Add a classic wizard hat to his ensemble and a longsword sheathed at his waist. Set the scene against a dramatic urban medieval backdrop, blending elements of gritty cityscape with gothic architecture. Ensure the colors are rich and vibrant, with strong contrasts to highlight the necromancer's mystical aura and the intricate details of his attire and surroundings.
