I walked in universes where the laws of physics were devised by the mind of a madman! And I watched universes freeze and creation burn! I have seen things you wouldn’t believe! I have lost things you will never understand! And I know things, secrets that must never be told, knowledge that must never be spoken! Knowledge that will make parasite gods blaze! So come on then! Take it! Take it all, baby! Have it! You have it all!
-From The 11th Doctor in “The Rings of Akhaten” (S7E07)
