A colossal obsidian fortress towers against a dramatic twilight sky, its jagged spires reflecting shades of deep purple and crimson. Shadows dance over the fortress walls, intricately carved with ancient runes that glow faintly in the dim light. Surrounding the fortress, a misty landscape of dark forests weaves around rocky outcrops, while a lone, winding path leads to an imposing, heavy iron gate shrouded in mystery.
