we obviously know what gandalf was doing the hobbit and the lord of the rings. but there is so much I personally don't know about him,. when did he and the other wizards arrive, what are all his powers, how old is he, what did he do before and after each of his big adventures, how did he get all of his different names, where did the name gandalf come from considering he holds a different name with the valar? what did he represent to tolkien? I personally would love to see a detailed video about gandalf. or if people want to share what they know that would be fabulous.
