L. Frank Baum's "The Life and Adventures of Santa Claus", a 1902 children's book, further popularized Santa Claus. Much of Santa Claus's mythos was not set in stone at the time, leaving Baum to give his "Neclaus" (Necile's Little One) a wide variety of immortal support, a home in the Laughing Valley of Hohaho, and "ten" reindeer—who could not fly, but leapt in enormous, flight-like bounds. Claus's immortality was earned, much like his title ("Santa"), decided by a vote of those naturally immortal. This work also established Claus's motives: a happy childhood among immortals. When Ak, Master Woodsman of the World, exposes him to the misery and poverty of children in the outside world, Santa strives to find a way to bring joy into the lives of all children, and eventually invents toys as a principal means. Santa later appears in "The Road to Oz" as an honored guest at Ozma's birthday party, stated to be famous and beloved enough for everyone to bow even before he is announced as "The most Mighty and Loyal Friend of Children, His Supreme Highness – Santa Claus".
