The planet Venurius is dying and to preserve the purity of their bloodline the inhabitants must find a new world. But where? There is one perfect host planet and its colonisation by the Venurians' changes the course of its history. Tainting pure Venurian blood by interbreeding with the indigenous people is frowned upon, but inevitable, and when trouble breaks out because of it, the consequences affect the host planet and entire planetary system. The Venurians leave their mark on the subjugated planet in many ways, leading to some of the greatest stories ever told, shrouded in myth and legend, being passed down through the millennia.
