Aquareine hesitated a moment whether to go on or turn back, but there was no escaping the sea devils behind them, and she decided the best way out of their difficulties was to bravely face the unknown Zog and rely upon her fairy powers to prevent his doing any mischief to herself or her friends.

So she led the way, and together they approached the archway and passed through it.
They now found themselves in a vast cavern, so great in extent that the dome overhead looked like the sky when seen from earth.

In the center of this immense sea cavern rose the towers of a splendid castle, all built of coral inlaid with silver and having windows of clear glass.
Surrounding the castle were beds of beautiful sea flowers, many being in full bloom, and these were laid out with great care in artistic designs.

Goldfish and silverfish darted here and there among the foliage, and the whole scene was so pretty and peaceful that Trot began to doubt there was any danger lurking in such a lovely place.
As they approached to look around them, a brilliantly colored gregfish approached and gazed at them curiously with his big, saucer-like eyes.

"So Zog has got you at last!" he said in a pitying tone.
