A pixel art depiction of a full-body medieval knight clad in a shimmering metallic blue armor, worn and slightly dented, reflecting faint glimmers of light. The knight exudes the aura of a once-great warrior burdened by defeat, with a solemn expression visible through a slightly open visor. He stands tall, gripping a massive, intricately designed sword planted in the ground before him, its blade chipped and showing signs of intense battles. His stance is heavy, as if weighed down by past failures. A flowing, tattered cape in muted gray-blue hues adds movement, contrasting against the static, dark background of a somber battlefield at dusk, with faint silhouettes of ruins and a crimson sky. Every pixel conveys a sense of lost glory and unshaken resolve.
