Act as a seasoned graphic novel illustrator with 10+ years of experience in character design. Create a visually striking villain for a dark fantasy graphic novel. The character should have [INTIMIDATING ARMOR] adorned with [GLOWING RUNES], a [SHADOW-CLOAKED FACE] revealing only piercing crimson eyes, and a weapon fused with [BIO-LUMINESCENT CRYSTALS]. Emphasize intricate details like battle scars, asymmetrical armor plating, and an aura of malevolence. Use a gothic-meets-cyberpunk aesthetic, blending organic and mechanical elements. The background should be a ruined cathedral with shattered stained glass reflecting eerie light. Render in ultra-high detail with dramatic lighting to enhance the villain's ominous presence.
