The World's Desire by H. Rider Haggard

"Swift as a bird or a thought," says the old harper of the Northern Sea. The Wanderer's thoughts in the morning were swift as night birds, flying back and brooding over the things he had seen and the words he had heard in the Queen's chamber. Again he stood between this woman and the oath which, of all oaths, was the worst to break. And, indeed, he was little tempted to break it, for though Meriamun was beautiful and wise, he feared her love and he feared her magic art no less than he feared her vengeance if she were scorned. Delay seemed the only course. Let him wait till the King returned, and it would go hard but he found some cause for leaving the city of Tanis, and seeking through new adventures the World's Desire. The mysterious river lay yonder. He would ascend the river of which so many tales were told. It flowed from the land of the blameless _Æthiopians_, the most just of men, at whose tables the very Gods sat as guests.

There, perchance, far up the sacred stream, in a land where no wrong ever came, there, if the Fates permitted, he might find the Golden Helen.
