Voiceover from Galadriel, as we watch a group of men carrying what appears to be a body wrapped in linens and chains: When Angmar fell, the men of the north took his body and all that he possessed, and sealed it in the high fells of Rhudaur. Deep within the rock, they buried him in a tomb so dark, it would never come to light.
Gandalf: Yes, there are tombs there.
Beorn: I remember a time when a great evil ruled these lands. One powerful enough to raise the dead. If that enemy has returned to Middle-earth, I would have you tell me.
Gandalf: Saruman the White says it’s not possible. The enemy was destroyed and will never return.
Beorn: And what does Gandalf the Grey say?
Gandalf is silent.
Beorn: Go now while you still have the light. Your hunters are not far behind.
We then see the Company arrive at the edge of Mirkwood, and Gandalf tells them he must leave.
29:18 – As Gandalf prepares to leave, he warns the others: This is not the Greenwood of old. There is a stream in the woods that carries a dark enchantment. Do not touch the water. Cross only by the stone bridge. The very air of the forest is heavy with illusion.
