Count Saint Germain is an elderly gentlemen, who puts on a charlatan-like act to make others think he's a travelling scholar and trickster. In reality, he is a wizard specializing in alchemy. He also may be immortal and from a different space or time. He possesses knowledge that would be considered heretical and eccentric and doesn't share his knowledge as few would understand or accept it.
