I am Death's Door!

If Chiron had not jumped as fast as he did, then the blade Emma stabbed through his back would have punctured his heart. 

However, at the same time, she fell to the ground, Coughing up blood. The contract Emma had with Chiron was a master-servant contract. 

This meant that the servant may never raise their hand on their master. If it were ever to happen, then the servant would die, regardless of how strong the servant was. 

And then came a loud laughter that echoed through out the Temple. This was a very familiar voice. After all, it was Abel's.

He immediately appeared from the ground. Chiron recognized him. He appeared behind her, "I hate your kind, but a deal is a deal."

He grabbed her by her mouth, and then he poured the content of a bottle into it. After which he made a certain symbol on her body.

*CRACK!*

Like egg against stone, Chiron felt a crack within his soul, and then came the shattering.
