You come up on it at dawn and those columns loom out of the mists like giants at the start of creation; made of this shining black glass stuff that they say's never been chipped nor broken nor shattered. But at the tops of them is a city, all the little houses and fountains tucked in with gardens hanging all around. And loud! Birds of every kind singing and screaming around you. The people are the same as you 'n me -- 'cept their rulers, of course. Strange folk, you'll never see 'em without their masks and gloves. But who's behind the masks? No one can tell."
