[GreatWarg]

The istari were not permitted to use their own powers for domination or for forcing the peoples of Middle-earth to see their way. They could only use their powers for good, such as Gandalf. Each istari had his own special powers, but they each had wisdom and magic. Saruman, however, grew corrupt with the ways of the Arda, and therefore disregarded their policies. Radagast used his powers to talk to animals and befriend them. Gandalf seemed to be the only one who trully fulfilled his quest, and therefore could return to Valinor.
