Cap 715: no time for explanations

After the heroes left and I left my orders to Diana and Vanessa, I gather Freya and my Familiars close to me while Vanessa is creating a temporary barrier using holy magic to prevent others in town from seeing us. 

"I have a way for all of you to help, you all have pure elemental affinities, but everyone's bond is with me." (I) 

"That means your power would have to be gathered within me to act together for this to work, which it won't." (I) 

"Your body wouldn't resist." (Nix) 

"Exactly, that's why I'm going to create a crystal with my blood through which everyone's power can be channeled." (I) 

"That will work?" (Ragnar) 

"The blood is still a part of him, so it should work." (Sakura) 

"I hope so because if it doesn't work I'm going back to the original plan and abandoning this place." (I) 

"None of us would want to hurt you, so there's no reason to do something so risky." (Freya)
