Claude remembered the ritual very well. From the beginning to when Len pulled out Eugene's werewolf heart, Claude carved that sight in his mind. It felt like he failed Eugene at that time. He was only grateful that Eugene pulled through. Len also managed to seal the moon energy in that heart.
A werewolf's heart was the most important organ to them. To 'cure' lycantropism, the wolf's Alpha must subdue and seal the wolf's moon energy. The best place for that seal was where all the blood of one's body flowed.
That was why they needed to cut out Eugene's heart.
Ah, Charles had long said it was a method for dealing with traitors. He knew about it since he had seen his own Alpha punish others through it. Then again, no one knew why Gunther Dreyfus, one of the Lords of Winter, allowed Charles to keep his werewolf heart. Charles was a traitor to everyone in the Lunavida pack. However, his Alpha didn't truly punish him.
