in the Story because she is a key element of the battle. At a later high ceremony of Old Ones, the Lady is missing and Merriman tells Will that her depleted power prevents her arrival, and she is beyond their magic to rescue but will return. She represents the Lady of the Lake, or the Lady of Avalon, King Arthur's sister, as they both embark on Arthur's boat Pridwen in Silver on the Tree. The Lady, like King Arthur, is affiliated with The Light and the High Magic. In Silver on the Tree, she initially can only communicate with Jane Drew, the one girl among the Six, telling Jane they share a special bond in being female, and calls her "Jane, Jana, Juno", referring to Jana (in Roman mythology, a variant form of Diana) or Juno, the queen of the gods. The Black Rider: One of the great Lords of the Dark, comparable to Merriman in power and influence. The Rider is the major nemesis of Will during his many trials. He patronises John Wayland Smith's establishment, where he meets Will for the first time and attempts to bring him over to the Dark. He is given one name by the humans in the story: Mitothin (a name connected with the jötunn Loki, who helps bring about Ragnarok). The White Rider: Another servant and Lord of the Dark, introduced in Silver on the Tree. The White Rider is almost equal in power to the Black Rider, and despite being feminine in her true form, often affects a masculine guise while attacking agents of the Light. She is revealed as disguising herself as Blodwen Rowlands, an "aunt" figure to Bran Davies. She acts kind and caring, to keep an eye on Bran while developing emotional bonds, while controlling events around Cader Idris, which means "chair of Arthur", and the Sleepers. Will Stanton hypothesized that the monochromatic 'colour' of the White Rider's robes, like those of the Black Rider, reflected the extremism of their evil—either darkened by their ignorance, or blinded by the brightness of their ideas. The Walker: A human who betrayed the Light and was cursed to carry the Sign of Bronze, one of six Things of Power that repel the Dark, through the centuries until the last Old One claimed it from him. The Walker was once Hawkin, a liege man and foster son of Merriman during the 13th
