Destiny's Revelation

Billions of years ago, a world named Selud was created at the same time as Earth was. Peaceful for the first two years, the people later crowned two men and two women as their rulers based on the virtues that their deity, Naria, had built the world upon. Another ten years until chaos erupted where King Gavin of Power betrayed Haley of Wisdom, Chas of Courage, and Rissa of Love. Followed by a war that lasted ten years, this leaders disappeared without a trace, leaving the world abandoned.
Now in the present, the world has divided into four countries with different ideas as to what happened and about the descendants of this leaders, descendants they call the Chosen. Randomly picked and suspected of being the Chosen, Zam, Linka, Fean, and Kayta are orphans who agree to journey into a dangerous swamp and a mysterious temple that will magically reveal whether they are the Chosen or not. But it all comes down to one secret: Gavin may have had a brother who may have been the one who started the war, and because of that, he may have a descendant who may be just as evil and twisted. With this secret coming to the light, doubt is everywhere and trust is nowhere to be seen.
Trust everyone, trust no one.
