Re: the wizards

It's said in UT that Ithryn Luin established some kind of misterious cults in the East, wich were long remembered afterwords (even after the fall of Sauron)

Of the Blue little was known in the West, and they had no names save Ithryn Luin "the Blue Wizards", for they passed into the East with Curunir, but they never returned, and whether they remained in the East, oursuing there the ourposes for which rhey were sent, or perished, or as some hold were ensnared by Sauron and became his servants, is not now known

Also:

Manwe summoned counsil to send three emissaries to middle-Earth.
"Who would go? For they must be mighty, peers of Sauron, but must forgo might, and clothe themselves in flesh so as to treat on equality and win the trust of Elves and Men. But this would imperil them with fears, cares, and weariness coming from flesh
...
But two only came forward: Curumo, who was chosen by Aule, and Alatar, who was sent by Orome. then Manwe asked, 'where was Olorin'? And Olorin, who was clad in grey, and having just entered from a journey had seated himself at the edge of a council, asked what Manwe would have of him. Manwe replied that he wished Olorin to go as the third messenger to Middle-Earth. But Olorin declared he was too weak for such a task and that he feared Sauron. Then Manwe said that that was all the more reason why he should gi, and that he commanded Olorin. But at that Varda looked up and said: 'Not as the third' and Curumo remembered it.

Curumo (Saruman) took Aiwendil (Radagast) because Yavanna begged him, and Alatar took Pallando as a friend (those two are Blue Wizards.)

Also there was very interesting statement - they went east together with Saruman. What does it mean? There was alternative version too, stating that after some time they have fallen and fell to Sauron-worship.
