Aeron was just a gardener and a Ghel, who are the Lord of Light's chosen people. He and his people were taken by the Ash soldiers into slavery. He was chosen with three of his friends, to maintain the royal gardens of Ashkeloth, the capitol city of Ash. When the King of Ashkeloth started to have troubling dreams, it was Aeron who calmed him and made him understand the meaning behind those dreams. So when the King elevates his status, things for him will become more difficult. But the King of Ash was but only one leader Aeron will have to contend with.
Together, Aeron and his friends will have to go through many dark times before it is over and survive, just as they flourished in the light. In the end, lives will be changed, and a path opens up into the future.
