The Callaeci peoples develop portal technology to travel between parallel multiverses and discover the Nimi peoples of the Kingdom of Nimi. The King of Nimi allows a Callaeci settlement in the Nimi province of Portgael in exchange for advanced technology, but as more Callaeci arrive, they establish a secret slave trade of Nimi for dire purposes.

When the King of planet Nimi dies, Prince Blaes is forced to overcome prejudices of his past. Alongside Nia, the enigmatic leader of an outlawed mystical order, Blaes must unite the warring Nimi and Callaeci peoples before a greater threat succeeds in their mutual destruction.
