Skyfall is a hidden kingdom, hidden in the cloudiest sky near Pyrrhia. Siren is an orphaned, curious Rainwing. She has one friend, Shardseeker. She learned about there being a hidden kingdom somewhere near Pyrrhia by a legend that she learned about where she was taught. She also learned about the season goddesses that lived there. She wishes to go there someday, so she and Shardseeker hear the call of Skyfall and go on a journey to see it. She later finds out that the Pyhhrian tribes have a conflict. She soon finds out who started it, so she and the dragon who started it have beef together. Will Siren and Shardseeker find a way to get rid of the dragon who started the conflict? Or is it too late to stop it on their own?
