PLOT TWISTS!
Ice sprites are a race that originally came from the dimension that the predators were banished to. They escaped persecution from the evil predator leader but they weakened the barrier in the process. In order to seal the predators forever, the reindeer must also banish the ice sprites.
Paprika was born a weak and frail baby barely surviving her birth. Her parents were desperate to keep her alive. So they performed a ritual in which they bathed their baby in the aura of the gate that separates the world of Foenum and the realm of the predators. In doing so, it granted their baby immense powers, such as almost endless energy and great physical strength. But in the process it weakened the barrier to the predator realm. Unfortunately for Paprika, in order to seal the predators forever, see must give up her powers and also banish her parents into the predator realm.
The sheep elders many years ago secretly stole a timid wolf pack from the predator realm and raised them to be obedient. But doing so weakened the barrier to the predator realm. In order to banish the predators forever, Pom must also banish her only friends and family, her dog pack.
Fred is the son of the predator leader (I think I mentioned this earlier in plot twists) and escaped the predator realm. But doing so weakened the barrier. In order to banish the predators, Fred must kill his father and then act as the vessel that corrupted him. Then Oleander must banish her only friend to the other realm to bring peace to Foenum.
Centuries ago, a hapless horse heard a voice from the void. It came from a dragon from the predator realm. The horse and the dragon communicated for decades through the void and eventually fell for one another. One day the horse grew tired of never meeting the dragon. So he sought an ancient power to bring his beloved into his world. Doing so weakened the barrier between realms. Many generations later, Tianhuo faces a dilemma, she can only banish the predators forever by sacrificing the dragon half of her race.
Texas secretly has another child named Montana who is suffering from a mysterious illness. The reason why cows travel is not for better pastures but to look for a cure for his daughter. In their travels, Texas accidentally opens the gate to the predator realm. The predator leader tells him that he has the cure for his child. To banish the predators, Arizona must kill her father who is possessed by the predator leader.
The predators escaped because of the actions of a few that weakened the barrier and eventually broke it. So to have peace many sacrifices must be made. The biggest plot twist? The story is an allegory for man's effect to climate change... dun dun dunnn!
