The Sword of Freedom

While the two siblings Laura and William are staying at their grandfather's house, they find a sword laying in a wooden chest. A strange symbol is carved into both the blade of the sword and the wood of the chest.

They soon find themselves in what looks like a dark and damaged parallel universe.

Here they meet a strange boy if you could call him that. He explains how there is an ongoing war in the country, Emalon Empire; the once great king has turned mad after the death of his wife and is now seeking revenge on all the people living in his empire. Guards were sent to burn down the villages and kill everyone in sight. So the people started fighting back and created a resistance called the Ridumarm.

William and Laura decide to join the fight and help this boy whom they slowly get to know stop the king once and for all before it's too late.
