Antonin made a quick gesture with one hand, as if throwing something away.
"Your bonding to Dolohov was Blood Magic, even if it didn't feel like it to you, based on your honestly given word to care for people and place. But then, the Castle has been there for so many years, it seems to have taken on a life of its own. The bonding of itself, I think, is more to allow you to be aware of all of Dolohov, wards, people, buildings, elves; all of it, since all is in your care. Ask Yuri the Ghost if you want. He's been around since Dolohov was a wide spot on the traders' paths and seems to know how the Castle thinks."
He smiled at Morag fondly, "As to the rest, you gave your word, I gave my word. What other sort of binding was necessary?"
