Epic realistic illustration with a cartoon twist, featuring dark colors and soothing tones, inspired by the atmosphere of Diablo 4. A foreboding landscape with ancient ruins, shrouded in mist and shadows, with mystical symbols glowing softly. Heroic figures, clad in intricate armor with vivid details, stand vigilantly, their expressions determined. A looming castle in the background, silhouetted against an ominous sky that hints at both danger and mystery. A mystical aura envelops the scene, inviting the viewer into a world both familiar and otherworldly.
