Quote from : Cities of the Plain Book

You call forth the world which God has formed and that world only. Nor is this life of yours by which you set such store your doing, however you may choose to tell it. Its shape was forced in the void at the onset and all talk of what might otherwise have been is senseless for there is no otherwise. Of what could it be made? Where be hid? Or how make its appearance? The probability fo the actual is absolute. That we have no power to guess it out beforehand makes it no less certain. That we may imagine alternate histories means nothing at all.
