Excerpt:

It was at the council that they discovered that the humans were going extinct. Of course, there was other business as well, but that quickly turned out to be the most important. As one griffin put it, “Without humans, no forest. Without forest, no golden griffins. And without golden griffens, eventually, no one else.”
Despite the obvious problem, no one could quite decide what should be done and when. Verbal fighting broke out, most bitterly between the dragons and the dwarves. The dwarves accused the dragons of eating the humans, and the dragons most bitterly retorted that they had not and perhaps the dwarves were using innocent dragons as a cover up. The stone griffins said a search party ought to be organized. The selkies didn’t know what to do, and said so, very loudly. Order was restored when the sirens said they would sing the humans back. Sirens being the most powerful singers, and often the most dangerous, everyone disapproved of that. Meanwhile, the golden griffins, who were the most endangered in the immediate future because of the humans’ disappearance, kept quiet. When High King Tambertin finally restored order, it was they who spoke first.
