Create an illustration of a lone warrior sitting on a rocky outcrop. The warrior wears a dark, ornate suit of armor featuring intricate designs, with a hood that casts a shadow over their face. Instead of a sword, they hold a staff that has a glowing crystal at its tip. The background should feature a stormy, twilight sky with swirling clouds in shades of purple and blue, creating a mystical ambiance. The color palette should be darker, focusing on deep blues, blacks, and hints of silver, avoiding any direct brand references.
