Sorcerer

The sorcerer is the antagonist in the second half of The Hollow Kingdom. He is the brother of Dr. Thatcher and dicovered goblins thanks to the revenge Marak took on Kate Winslow's gaurdian, Hugh Roberts. The sorcerer is described as "unremarkable in every way" except for the fact that his pupils are red. He captured Hulk using a wolf trap with Egytian hieroglyphics on it in order to summon other goblins to him as slaves using Hulk's blood. He managed to call around sixty goblins before he ran out of blood and Kate beheaded him. Other than the goblins he had also enslaved two wizards who were later freed by Kate and took his body to dispoe of it and carry out their revenge on him.

The sorcerer's magic required living things, many of which he kept captive until he used them or they starved to death. These included a pair of wolves, rats, three foxes, many kinds of birds, a one-eyed bear, poisinous snakes, a monkey, a white mouse with one paw missing, and a human child. The monkey and mouse as well as the wolf and her pup followed Kate back to the goblin's kingdom where they lived until their deaths. Meanwhile Kate brought the child along and let the King's Wife Charm name her Matilda after one of his favorite Wives.

Another one of the sorcerer's spells was a warning that would cry whenever a woman approached. It was the hand of an infant that he had pinned by the door and he explained to Kate that it cries because it is still searching for its mother.
