Why did the Ithryn Luin go?

[Lord of Angmar]

I am of the opinion that they probably went into the far East with good intentions; perhaps, as has been said, to gain support from the Easterlings in anticipation of a final war with the Dark Lord, or perhaps to bring the Avari at last to Valinor (an interesting idea which I had not before pondered). However, I think they ultimately strayed from their goals, much as Radagast and Saruman forsook their purposes. As for the final fates of the Blue Wizards, I will quote Mr. Bilbo Baggins:

Where many paths and errands meet
And whither then? I cannot say.
