In the Northern Darkness there is a fish, and its name is Kun. The Kun is so huge that a single pot... ahem, who knows how many thousands of miles across it is; when it transforms into a bird, its name is Peng. The back of the Peng stretches for who knows how many thousands of miles, and when it rises in fury, its wings are like clouds hanging from the sky.
This is Zhuang Zhou’s description of the Kun in *Free and Easy Wandering*. Naturally, the Kun Ye Feng summoned with the Expecto Patronum could not possibly be that massive; the phantom he summoned was merely a miniature version. If he were to truly summon a real Kun, it would remain uncertain whether the Black Lake could even contain it.
Yet, even a miniature phantom was something these Merpeople could not withstand. With a single swallow from the Kun, all the Merpeople were instantly wiped out. As the Kun’s phantom vanished, he also received a considerable amount of information.
