Amadeus held up a finger for Rhys' to wait a moment. Now that Joseph was completely out of the Haven, the Elder Tremere had things to set up before they continued. He was used to ignoring Ariel walking in while he was in the middle of something and not losing focus but that was because he trusted his lover completely and easily tuned him out while doing so. He also had no problem with Ariel knowing not only Tremere secrets but his secrets and the changes he was about to do to the ritual they were about to do were very much his own and a Tremere as old as Amadeus very much guarded those secrets.
The wards on Henry's Haven had faded in his absence so it was safe for Amadeus to lay out his own. He drew out several in his own blood and once activated they glowed for a moment before the blood on the back of the study door that he had drawn them out on seemed to be absorbed into it. Now that the study was soundproof, Amadeus pulled up a shield around the room so that nothing was coming in or out. Not that he planned on summoning up any demons that might escape. The shield being small, barely nothing compared to what he had pulled up the night of the fire, it was just background noise in his mind to keep it going.
Once that was done, he turned back to Rhys and gave him a nod. It was good that he had fed properly. Amadeus was planning on spilling the most blood here but the younger Tremere would still have to use his own since he was the one with the connection to Henry. Even with the ring, the connection of blood was so much stronger. Picking up the knife he had brought, the elder Tremere sliced open not the palm of his hand but his wrist before holding it over a metal bowl. He allowed it to fill a bit with his more powerful blood before allowing the wound to close. Then he passed the knife over to Rhys. "Just your palm will do and it doesn't have to be much. We just need some of yours to mix in with it to offer up the sire connection. Then drop the ring into the bowl for the personal connection."
