Mating ceremony (part 3)

Ravina wasn't sure what she was going to witness next, but a priest stepped into the circle and began to speak to the bride and groom privately. 

"He is preparing them for the mating now. The groom will leave a mark of teeth and the bride will leave a mark of claws," Malachi explained. "Will you be alright to watch?" 

"How can you leave a mark if you can heal?" She asked. 

He smiled amused. "There is an instinct element to finding a breedmate but also a magic element. So when two souls come together willingly, ready to share a part of themselves the magic happens that bonds them." 

Magic?
