Re: The White Council
Nothing sinister about it. The council chose Saruman as the leader as opposed to it being a forced decision. Saruman was considered to be the wisest in knowledge of the Enemy and the ring-lore but this was also his weak spot that lead to his eventual downfall. Galadriel being very perceptive and having lived in Valinor for part of her life likely suspected that Gandalf was the wizard most likely to fulfill his purpose and not fall astray from the path. She may even have know of him as Olorin in that time.
Most of the information on the council comes from the Appendices. It consisted of the five wizards, Galadriel and other chief Eldar. Elrond was likely a member, perhaps Cirdan as he did hold a Ring at one point. Celeborn is another likely member and possibly Glorfindel. There were four meetings recorded. The first was about finding out more about the Necromancer of Dol Guldur but Sauron fled before they could determine anything. The second meeting happened after Gandalf entered Dol Guldur, found Thrain and discovered it was really Sauron. Gandalf urged an attach but Saruman over-ruled it as he was secretly searching for the Ring himself. The third meeting happened while Bilbo visited Rivendell on the quest of Erebor. Finally it was decided to attack Dol Guldur which was why Gandalf left Thorin and Co. as they entered Mirkwood. The council drove out the Necromancer but this was just a strategic withdrawal to Mordor. The fourth meeting came to naught. Saruman lied in declaring that the Ring was long ago tumbled down the Anduin into the sea. By now other members of the council were feeling a bit of a nagging doubt in Saruman's actions and intentions.
