Dark fantasy oil painting artwork, widescreen 16:9 layout. The monumental iron fortress of Angband, the underground citadel of Morgoth, strictly built according to J.R.R. Tolkien's lore. In the center, giant, terrifying iron gates and black obsidian walls carved directly into the dark mountain roots. The sky above is a pitch-black heavy void choked with toxic ash and glowing red volcanic fog. Massive chasms around the fortress reveal deep subterranean fires and slow rivers of orange magma, casting dramatic sharp highlights on the cold metallic surfaces. Painted with heavy, rich textured brush strokes, moody fine art lighting, epic fantasy book illustration style, high contrast, 8k resolution. NO Thangorodrim peaks, NO 3D render look, NO faces, clean artistic composition
