His name was Heidel von Hymack. Some kissed his hand and worshipped as he passed by; others reviled him, threw stones and tried to destroy him. He was both a walking antibody, a living pool of remedies – and at the same time a repository for every foul disease in the Universe. Often, without meaning to, he killed. Oftener still, with preparation, he cured. There was only one of his kind in the Universe – and that was why it became dangerous. Many wanted him, needed him to exploit a power game within the Empire. Some wanted him dead, others for a living scientific experiment. The hunt was on, for the man who was both saint and demon.
