Create a cinematic dark fantasy action scene in a ruined cathedral hall: a female armored knight-mage crouches in a defensive lunge on the left foreground, wearing ornate dark steel and leather plate armor with a long cream-and-black tabard, one arm extended behind her gripping a spiked mace or morning star crackling with golden magic sparks, the other arm braced forward behind a round glowing shield rimmed with warm light. Opposite her in the right midground is a massive headless stone golem, built from cracked gray masonry plates and bound with broken chains, charging with one huge fist raised and rubble falling from its body. Set the battle inside a grand, damaged palace-cathedral interior with towering arches, carved stone columns, tall broken windows, gold-trimmed marble floor in circular geometric patterns, scattered chunks of stone, dust, and debris. Use dramatic backlighting from a bright arched window behind the golem, warm golden magical highlights on the shield and weapon, deep shadows, volumetric dust beams, realistic textures, high-detail armor and stone, dynamic low-angle wide composition, shallow cinematic depth, epic game-cinematic realism, 16:9 widescreen, no text, no UI.
