They were heading straight in now toward the solid rock, which must have been well over a hundred feet tall, and not until they were within fifty yards of it did Ardita see their objective. Then she clapped her hands in delight.

Then they were riding at anchor in a miniature world of green and gold, a gilded bay smooth as glass and set round with tiny palms, the whole resembling the mirror lakes and twig trees that children set up in sand piles.
