Fenrir

In the dark forests of the North, there prowled a mighty beast known as Fenris, the wolf born of giants. His fur was black as night, and his eyes gleamed like two burning embers. Bound by chains forged by the gods themselves, Fenris grew stronger with each passing day, his rage as wild as the storms that swept through the mountains. It was said that when he finally broke free, the very earth would tremble beneath his paws. For Fenris was no ordinary wolf, but a creature destined to devour the sun and plunge the world into eternal darkness.
