With the Valar came lesser spirits of the Ainur, called the Maiar. Melian, the wife of the Elven King Thingol in the First Age, was a Maia. There were also evil Maiar, including the Balrogs and the second Dark Lord, Sauron. Sauron devised the Black Speech (Burzum) for his slaves (such as Orcs) to speak. In the Third Age, five of the Maiar were embodied and sent to Middle-earth to help the free peoples to overthrow Sauron. These are the Istari or Wizards, including Gandalf, Saruman, and Radagast.
