The Geste of Beren and Lúthien

[Lines 2,064 – 2,088]

Men called him Thû, and as a god
in after days beneath his rod
bewildered bowed to him, and made
his ghastly temples in the shade.
Not yet by Men enthralled adored,
now was he Morgoth's mightiest lord,
Master of Wolves, whose shivering howl
for ever echoed in the hills, and foul
enchantments and dark sigaldry
did weave and wield. In glamoury*
that necromancer held his hosts
of phantoms and of wandering ghosts,
of misbegotten or spell-wronged
monsters that about him thronged,
working his bidding dark and vile:
the werewolves of the Wizard's Isle.
From Thû their coming was not hid;
and though beneath the eaves they slid
of the forest's gloomy-hanging boughs,
he saw them afar, and wolves did rouse:
'Go! fetch me those sneaking Orcs,' he said,
'that fare thus strangely, as if in dread,
and do not come, as all Orcs use
and are commanded, to bring me news
of all their deeds, to me, to Thû.'

[For those who are unaware, Thû = Sauron]
