Create a highly detailed fanart of King Irmin as a playable character in *Genshin Impact*. Portray him as a tall, imposing figure with regal, dark armor adorned with intricate runes that hint at his connection to Forbidden Knowledge. His eyes should glow with an eerie, otherworldly light, symbolizing the dangerous power he wields. His weapon is a massive, ancient sword that radiates dark energy, and in the background, a shadowy outline of the Irminsul tree looms, intertwining with mysterious symbols. The environment is a mix of ruins and corrupted landscapes, echoing the fall of Khaenri'ah. Capture the essence of a fallen king with immense, but cursed power, blending elements of royalty and darkness.
