Sentinus sat, god-like on a normal stool. As soon as he touched it the chair transfigured into a black throne. In his hand was the Elder Wand, his source of impervious power. In his other hand were his silver gauntlets. He surveyed the little headmaster and laughed inside. This man was no threat to the Grand Sentinus, in possession of the Elder Wand.
"Hogwarts can no longer continue as it is," he said, a tone of dominance littering the smoothness of his voice. "There is a cause Hans, and I want you in on it."
Hans smiled. "I have planned to join since you came from Siberia." And hans, the little old man drank some tea before kneeling at Sentinus' feet. It was almost cruel, such a good soul kneeling before a cruel master.
"I pledge myself to The Family." He slurped tea when he thought Sentinus wasn't looking.
