Can a prophecy stand after two-thousand years?

At the death of King David, his many children from his concubines began to cause havoc for King Solomon and the growing kingdom. The Solution was mandated, all children of King David not ordained by decree would be sent away. The offspring would be allowed provisions and wealth, but they were never to return to Jerusalem.

The eldest son of King David and a concubine made a decree of his own, they would begin their own kingdom in the land of Gallaecian. Several years before, a prophecy had been given to the concubine Janica. Her unborn child from King David would bring about promise, hope, and a new start for them.

King David’s words had been spoken; “And she will have a gift of song and healing for all the generations, as long as they stayed true to our God.”

But, two thousand years later, King Albert, like his father before him, despises the faith and practices of worship to God, refusing to do what is right. The Songmistress and rabbi need to convince the king that it is time to return to his God or the fate of Princess Jerusha and his kingdom will be at the hands of the evil Goreans.

On the banks of the Black Sea lives a young girl with a gift of healing and dreams of prophecy, but they only bring her troubled thoughts of her past; who she might be and what the dreams mean for her future.
Can the prophecy still hold true if the days of repenting are called upon? Will God once again turn his face to the sons of David, or will this be the end of Kingdom of Gallaecian?
