Sirius stepped forward, his body blurred as he appeared in front of the blood-stained wall. Putting his snout near the dried blood, he sniffed.
Suddenly, he looked up. His eyes had darkness flowing within them as he seemed to look through the countless walls and obstacles as he locked onto an individual.
"Found you," Sirius whispered. His blood boiled as all the pent-up anger and frustration burst out.
"Awoooooo!!!" A loud howl reverberated in the corridor as Sirius showed his full power. His claws extended further as his body grew even more.
The skin underneath his fur squirmed. Dark and dull bones tore out of his skin as blood dripped on the ground. The bones appeared behind his elbows and on his back.
These were the natural weapons of a werewolf and in Sirius's case, these bones were filled with an immense amount of energy. The bones were condensed of the darkness contained in his blood and were the physical manifestation of his strength.
