When evening in the Shire was grey
His footsteps on the Hill were heard;
Before the dawn he went away
On journey long without a word.

From Wilderland to Western shore,
From northern waste to southern hill,
Through dragon-lair and hidden door
And darkling woods he walked at will.

With Dwarf and Hobbit, Elves and Men,
With mortal and immortal folk,
With bird on bough and beast in den,
In their own secret tongues he spoke.

A deadly sword, a healing hand,
A back that bent beneath its load;
A trumpet-voice, a burning brand,
A weary pilgrim on the road.

A lord of wisdom throned he sat,
Swift of anger, quick to laugh;
An old man in a battered hat
Who leaned upon a thorny staff.

He stood upon the bridge alone
And Fire and Shadow both defied;
His staff was broken on the stone,
In Khazad-Dûm his wisdom died.

I have to add: Tru Wisdom Never die! The grey becomes the Wight!
