Consider these passages:

The land had changed. Where before the green dale had lain, its grassy slopes lapping the ever-mounting hills, there now a forest loomed. Great trees, bare and silent, stood, rank on rank, with tangled bough and hoary head; their twisted roots were buried in the long green grass. Darkness was under them. Between the Dike and the eaves of that nameless wood only two open furlongs lay. There now cowered the proud hosts of Saruman, in terror of the king and in terror of the trees. They streamed down from Helm's Gate until all above the Dike was empty of them, but below it they were packed like swarming flies. Vainly they crawled and clambered about the walls of the coomb. seeking to escape. Upon the east too sheer and stony was the valley's side; upon the left, from the west, their final doom approached.
...
The Orcs reeled and screamed and cast aside both sword and spear. Like a black smoke driven by a mounting wind they fled. Wailing they passed under the waiting shadow of the trees; and from that shadow none ever came again.
...
He turned and gazed in wonder, first at the wood and then at Gandalf. 'Once more you come in the hour of need, unlooked-for,' he said.
'Unlooked-for?' said Gandalf. 'I said that I would return and meet you here.'

You gaze at me
And turn to Him. - everyone looks to Gandalf for an explanation
You hoped for neither. - no indeed, both were unlooked for

I swallow light, - being a dark dark forest
I swallow foes. - Orcs
I'm not the final doom. - no, Gandalf and Erkenbrand are described thus but the forest is not.

I serve myself. - indeed, the huorns do what they would. They helped out in the battle but only for their own revenge.
I come and go. - without warning.
I do not parley. - silent things, don't negotiate with Saruman.


Saruman and the Ents are a little Macbethan. "I will not be afraid of death and bane till Fangorn Forest come to Isengard!".

Yeah.

I'm sorry if the riddle and the clues were misleading. I thought the riddle would be pretty simple, as it's based on the text elements. But maybe it was too muddled a way to present the topic.

Over to you now! Well done!
