The Three Fair Ladies

Once upon a time, a prince rode through the wood, regaling the animals and trees with songs in praise of his true love.
"She sings more sweetly than thee, little bluebird," said the prince. "I'll wager my heart there's no lady more beautiful in all Azeroth!"
Just then, a bluebird alighted in his path, transformed itself into a resplendent fairy damsel and accepted his brash challenge.
The prince tried to rescind his words, but a wager spoken before a fey spirit cannot be unsaid. The damsel said that she would show him three fair beauties in that very wood and if his lady proved superior to them all, the fey would bless his wedding. But should the prince speak falsely, he must yield his heart to the shapeshifter's dagger. The damsel showed the prince a spring nymph that enticed his lust and a dryad that awakened his wonder. As splendid as they were, the prince swore that neither was as fair as his love and he spoke truly from his heart.
"But is she more beautiful than I?" said the damsel at last. The prince looked upon her dark eyes, her shapely form, and the sapphire feathers strung through her midnight locks.
At last, after great deliberation, he said, "Aye, even more so than thee."
The lady transformed into a bluebird and flew away, and the relieved prince was spared his life. The prince married his true love and ruled his kingdom, but for the rest of his days, he never looked upon her or anything else of beauty without yearning for the fairy damsel who possessed his heart as surely as if she had carved it from his chest.
