Where the Power of the Dark Lord is Shown

As the company enters into Lothlorien, the wooded elf-world, Gimli refuses to be blindfolded, as Haldir the elf demands. Ultimately Aragorn insists that they will all walk blindfolded--even Legolas, despite being an elf himself.

"Alas for the folly of these days!" said Legolas. "Here all are enemies of the one Enemy, and yet I must walk blind, while the sun is merry in the woodland under leaves of gold!"

"Folly it may seem," said Haldir. "Indeed in nothing is the power of the Dark Lord more clearly shown than in the estrangement that divides all those who still oppose him."
