Where is Radaghast????

[Guildo]

Ive always been curious about old Radaghast the Brown Gandalfs brother, we here him breifly mentioned a couple times in the books, but i feel if any he is anything Gandalf he has stayed very busy and has something to do with the ring war, after all thats what the where sent to middle earth for.
We know them as Saruman the white (1), Gandalf the Grey (2), and Radaghast the Brown(3), but after Gandalf became the white and Saruman was over thrown would radaghast have not become Radaghast the grey?????
i also feel he made a breif aperiance in the chapter "the grey Havens" ..... "as they came to the gates Cirdan the Shipwrite came forth to great them. Very tall he was, and his beard was long and he was grey and old, save that his eyes were keen as stars; and he looked at them and bowed, and said:'All is now ready."

tell me what you think
