The Obsidian Citadel

A lone knight in ornate, battle-worn armor stands at the edge of a colossal, crumbling obsidian citadel. Eerie, spectral figures drift through the shattered archways, their forms indistinct and sorrowful. The sky above is a turbulent swirl of deep purples and bruised oranges, hinting at a forgotten cataclysm. This scene is rendered in a dark fantasy style, with painterly textures and dramatic, gothic illustration elements, evoking a sense of melancholic grandeur.
