Merlin's Mirror, by Andre Norton. A stand-alone novel, unrelated to any of her other works. (From the back cover):
Here is Merlin, half-star-born, gifted with the advice of an alien intelligence, given the task of renewing civilization and starting humanity again up the ladder to the stars.
Here is Arthur, unaware of his stellar heritage...
and here, too, is the Lady of the Lake, akin to Merlin in that she is also a listener to the music of the spheres and obedient to a celestial command post.
