An epic knight, clad in ornate, gleaming armor etched with ancient runes, holding aloft a magic sword that glows with an ethereal blue light, stands resolute at the battlements of a colossal, gothic-style castle. The castle's stonework is intricate, with gargoyles and statues lining the parapets, and banners fluttering in the wind. The knight is viewed from behind, his silhouette stark against a fiery sunset, emphasizing his heroic stance. Below, a vast horde of fantastical enemies - orcs, goblins, and dark sorcerers - surge towards the castle, their weapons and eyes glinting with malice.

The air is thick with tension and smoke, the ground scarred from previous battles. Capture this moment in the highest detail, with hyper-realistic textures, reflective surfaces on the armor, and an atmosphere of impending battle
