The Royal Wizard of High Norland

Known as Great Uncle William to Charmain Baker

In House of Many Ways
The Royal Wizard of High Norland is an old wizard, who is sent away to be cared for by the elves when he falls sick (this is discovered to be caused by Lubbock eggs.) It is arranged that Charmain, a distant relation, will take care of his house - the house of many ways - while he is away. Charmain knows him as Great Uncle William and though he is not present in the house, he leaves magical instructions for Charmain if she has trouble managing things in the house. His voice is described as kindly and he is well respected by many, including the Wizard Howl.
