Dragons Imortal- Dawn and Dusk

Dawn and Dusk live on the island of Jamobala and every 3 years a town meeting/far is tradition. After the fight between the last two known dragons in Jamubala and Marlablico a prophesy is made. Two worthy friends will travel in the uninhabitable jungle and find an ancient magic.

Will Dawn choose the life of a hero or will she choose the path of evil.
Will Dusk choose the life of a hero or will she choose the path of evil.

How will they use the ancient powers? Will they stop the darkness that spreads on the two peaceful islands.
