The Hidden Kingdom

About
The Hidden Kingdom is about Queen Glory, an adult RainWing, challenging the RainWing throne because Queen Magnificent is too lazy to find and help the lost RainWings, who were taken by the NightWings. She won, and prepared a RainWing army to save the lost RainWings and Deathbringer. At the last part, it was mentioned that the volcano erupted and the NightWing island was destroyed and Starflight's eyes were blinded because of Morrowseer's fire.
