I've been following these fascinating posts & enjoying everyone's input on this crucial point. Capturing the feel of Middle-earth means we have to tread lightly where magic is concerned, & even I don't allow anyone to play any of the

. That said, however, it's your game & do what works for you.
I only want to add a quick point about the
Ithryn Luin (Blue Wizards) - from
UT:
In a letter written in 1958 my father said that he knew nothing clearly about ‘the other two,’ since they were not concerned in the history of the North-west of Middle-earth. ‘I think,’ he wrote, ‘they went as emissaries to distant regions, East and South, far out of Númenórean range: missionaries to enemy-occupied lands, as it were. What success they had I do not know; but I fear that they failed, as Saruman did, though doubtless in different ways; and I suspect they were founders or beginners of secret cults and “magic” traditions that outlasted the fall of Sauron.’
Tolkien wrote "fear" & "suspect," & you can read this in more than one way. It's just possible that an LM who wishes to include Alatar and/or Pallando can say that they/he returned from the East after all. In my own game, I commit the unpardonable sin (gasp!) of changing the story so that the emissaries of the Enemy corrupt Alatar, who does establish a secret cult, betrays & murders his friend Pallando, & returns westward. It's a stretch, but IMHO, he provides a cool foe to confound the heroes.
