Dark Fantasy Spellblade at Sunset

Create an epic dark-fantasy cinematic key art scene in a wide 16:9 format. A lone armored spellblade, {argument name="character name" default="Hermes"}, stands full-body in the foreground on wet ruined stone, facing the viewer in a heroic stance. The character wears ornate blackened steel and bronze plate armor with layered leather belts, pouches, engraved pauldrons, tall boots, and a tattered windblown dark navy cloak and scarf. Their face is deliberately obscured by a soft rectangular blur, while dark hair is visible above it. In the left hand they hold a long silver sword angled downward; in the right hand they raise a twisted black mage staff topped with a bright circular blue magical sigil, glowing runes, sparks, and swirling energy. The background is a vast gothic fantasy landscape at sunset: misty valleys, jagged snowy mountains, a distant cathedral-like castle with spires, ancient ruined arches and towers on the left, broken statues and rocks on the right, and low fog drifting across the ground. Lighting is dramatic, with orange-pink sunset clouds behind the mountains contrasted against cool blue magical light from the staff reflecting on armor and puddles. Use ultra-detailed realistic digital painting, high contrast, volumetric fog, cinematic composition, sharp armor details, moody atmosphere, no text, no watermark. Customize the sky mood as {argument name="sky mood" default="stormy orange and violet sunset"}, the magic color as {argument name="magic color" default="electric blue"}, the armor style as {argument name="armor style" default="ornate dark medieval plate armor"}, and the background landmark as {argument name="background landmark" default="distant gothic castle in the mountains"}.
