Create an artwork f a black griffon, a mythical creature with the head of an eagle and the body of a lion. The griffon should look fierce, protecting its young from an unseen threat in the background. The scene should be dark and stormy, with lightning and thunder cracking in the sky. The griffon's wings should be flared, and its claws extended, ready to attack. Use a dramatic lighting effect to highlight the danger of the situation, with the griffon's eyes blazing with determination and the young ones huddled underneath it. The young griffons should be crying out in fear and the griffon should look as if it is ready to unleash its fury to protect its young ones. The overall mood should be ominous with a sense of mystery and foreboding in the air
