Dense Fog Necromancer in an Oil Painting

An imposing necromancer in a weathered cloak stands in a moonlit clearing, dense fog curling around twisted graves and skeletal trees. Painted in an old-master oil painting style with thick impasto brushstrokes, deep umbers, muted greens and slate greys, a pale glow from arcane sigils on a bone-staff illuminates gaunt features and hollow eyes. The fog swirls, softly revealing and concealing the scene, with subtle chiaroscuro lighting and a somber, eerie atmosphere.
