[Keeper of Dol Guldur]

Not to put a damper on one of the replies, but Felagund changed Beren's shape into that of an orc, and Luthien made him look like the recently slain Draugluin. In both instances it was elvish chant.

Beorn didn't know any elves powerful enough to do that. By the time he came around (which could have, I suppose, been really far back) elves that powerful simply didn't exist (except Galadriel).

I had forgotten the real world meaning of Beorn, and the double play. Good ol' J. R. R. T., always the most clever. With wordplay like that what's-her-Harry-Potter-face ought to give up the whole series and her face fill with green envious smokes until she can't take it anymore. . .did I just go into a Potter-bashing kick? Oops!

But anyway, Radagast. Good fellow as far as wizards go. Master of shapes and hues. Talked and walked with the animals. So did Beorn. Connection? Likely. If not, he's still the toughest of them all. (Okay, discluding Aragorn, Faramir and those types).

Later fellows!
