[Macalaure]

The ones that fell open were the Silm:

The orcs and the wolves went freely through all the North, and came ever further southward into Beleriand, even as far as Nan-tathren, the Land of Willows, and the borders of Ossiriand, and none were safe in field or wild.

Seemingly an advice to not go out and stay at home.


and, after a while, the Fellowship:

'That is true,' said Legolas. 'But the Elves of this land were of a race strange to us of the silvan folk, and the trees and the grass do not now remember them. Only I hear the stones lament them: deep they delved us, fair they wrought us, high they builded us; but they are gone. They are gone. They sought the Havens long ago.'

What could this mean?
