The Dragonet Prophecy

The Brightest Night
It is confirmed in the book, by a lost letter Thorn had never received on time, that the mountain has some significant importance in the story. In the letter, the dragon of Jade Mountain is the NightWing dragon Stonemover, Sunny's father. He is found there inside, residing on the ground, unmoving, yet living.
