It was hard not to notice all those nervous ticks of Rhys' coming back. It also wasn't hard to follow his line in thinking since Amadeus seemed to be bringing up a lot of things that Joseph had neglected to point out before bedding the fledgling. "In Joseph's defense, one night does not a blood bond make." After all, Amadeus himself had fed on Ariel their first time before knowing what he was about to tell Rhys. "And he may believe I already told you." Which could have been the case.
"A blood bond is formed when a Kindred feeds from another three times over a course of time. Three times in a night won't do it but three days is close enough together to do it. The one who becomes bonded becomes completely devoted to the one they are bonded to. It's a bit like being a ghoul but ramped up to a hundred considering the power it gives one over another Kindred. Not how you want to start a relationship since you wouldn't know if the feelings are yours or because of the bond." Which was why Amadeus had been able to understand when Ariel had been concerned about them forming one since they were already burning so hot and fast. The house fire between them had not needed gasoline poured on it.
"The blood bond has been used by the Tremere for centuries to keep members of the clan loyal and keep secrets safe. It's called the pyramid. Instead of being blood bonded to one, you'd be bonded to several of the high ranking Tremere. Only the pyramid is broken. The Chantry in Vienna, which was one of our largest and most important ones, was raided. Destroyed. When it was, the pyramid broke. Which is why you have not been blooded in." And well, Amadeus had broken his own bonds long ago.
Amadeus shifted and lean forward before he continued. "I'm telling you all of this for a reason. When the pyramid broke, it did something to our ability to form bonds. Some backfeed with our magic. There's many who believe in the pyramid that are trying to fix it but for now, the Tremere hold so great a secret that even I did not know if it until recently. It's one that you can not tell Joseph but you need to know."
A pause.
"The Tremere can no longer form blood bonds. Neither to another nor to us. The Blood will not take in such a way for us anymore."
