NightWing Exodus
The NightWing Exodus was the journey the NightWings took to the Rainforest Kingdom to live with the RainWings, taking place in the end of The Dark Secret. The village they currently live in is called the Night Village.

History
Glory, not yet Queen of the RainWings, noticed that RainWings were disappearing, later figuring out they were being kidnapped by NightWings to be studied for their venom. Glory then participated in the Royal RainWing Challenge to become queen in order to get the dragons back, and succeeded. She then began to plan how she would get the captured RainWings back.
When Starflight was captured by the NightWings for false-prophecy-dragonet training, he figured out that the NightWings were planning to attack the RainWings to claim the Rainforest Kingdom for their own, as their current home was in danger of being the site of a massive volcanic explosion. He used a dreamvisitor to tell Queen Glory the NightWings' plan.
Before he went back to the Rainforest Kingdom, he overheared that the NightWings were going to attack the RainWings that very night. Starflight escapes into the Rainforest Kingdom to warn Glory and the RainWings.
Starflight suggested that instead of attacking the NightWing, the RainWings should defend the tunnel and take the NightWings out one by one as they came through, but Glory decided to attack because they also needed to save the missing RainWings. When she brought the other Dragonets of Destiny, they meet Greatness in the hallway leading to Queen Battlewinner's cave. They go inside with Greatness, where they find Battlewinner trying to use armor that Starflight's father, Mastermind, made that carries lava so she can lead the attack against the RainWings.
She notices Glory, who says she will take her RainWings back and protect her Rainforest from the NightWings, but Starflight suggests that the NightWings accept a new queen, Glory, and move to the Rainforest if they promise allegiance. But Battlewinner wanted to save her tribe, and tried to attack Starflight and Glory. She dies from the IceWing frostbreath inside of her, and The NightWing Exodus begins as the NightWings all meet at the Rainforest Portal. The Dragonets make the NightWings pledge themselves to Glory as a queen as they go through.
