The Shadow quotes from Doctor Who

The Shadow

I too serve a Guardian. A Guardian equal and opposite in power to the one who sent you. The Black Guardian, he who walks in darkness! And you are in the Valley of the Shadow!

The Shadow

Once the Key is ours we shall set not two small planets, but the two halves of the entire cosmos at war, and their mutual destruction will be music in our ears! Unlike others, it is not power we seek, but destruction that we glory in.

The Shadow

I know you. And I know there is a want of patience in your nature.

Yes, fools rush in...

The Shadow

[Interrupts.] Exactly.
