Down I fell, through depths of empty space set here and there with glittering crowns of stars.

Down for ten million miles and ten times ten million, till at length I hovered over a place of soft, unchanging light, wherein were Temples, Palaces, and Abodes, such as no man ever saw in the visions of his sleep.

They were built of Flame, and they were built of Blackness.

Their spires pierced up and up; their great courts stretched around.

Even as I hovered they changed continually to the eye; what was Flame became Blackness, what was Blackness became Flame.
