King of Despair

Kai Trisan is the heir to the throne of Durnatae. And for years, Kai has lived a normal life, until one day, his life takes a drastic turn and he unveils a power. Soon, Kai is found between the wall and the sword when he begins to realize that his powers keep growing stronger, more difficult to hide and if he can't hide them, people will find out. And hunt him for that. And things begin to get worse for him when creatures that are only found in the Island of Nightmares come to haunt him.
Tye Trisan is Kai's younger brother, and he has a secret of his own only a few people know. Living a life in the shadows, he joins a team to stop a prophecy from becoming free. In his way, he meets somebody that might become his salvation.
Sue Mobecc is the leader of a group of Berserkers--the name people with rare powers have been given. When she hears that the heir of the country is destined to bring the end of the world, she sets to find a way to stop him. She joins with the prince, and like him, she hides a secret that might endanger her life if anyone came to hear it.
