The Baron floated closer to the Headmistress and said "Naturally, I was not pleased that I was the last to know of a new ghost in the castle and I demanded that I be introduced to the spirit. So along we went with Sir Nick to the Spirit Room in the castle where my Lady Helena and the good Friar were conversing with Isfret. It was obvious to Isfret that I was not a ghost to cross, and he said a few inaudible words in Egyptian that made my chains vanish. Relieved that I no longer had to carry the burden of the chains, I insisted, to the delight of all, that Isfret be allowed to join the ghosts at Hogwarts."
