Haido had bought the Book of Gelel from a merchant overseas, and used it to look for the Gelel vein for powers to rule the world, which led him and his knights to where the vein rests. He and his subordinates, Fugai, Kamira, and Ranke, attacked Temujin's village (although Temujin didn't know about it at the time). The reason Haido attacked Temujin's village was to obtain the stone of Gelel, which he believed was in Temujin's village. He killed everyone in the village, including Temujin's parents. When he found Temujin, however, he saw potential in the boy and took him as his underling. Haido trained Temujin to become his minion and help him to find the Vein of Gelel.
