Blood will flow in this crossover event which pulls from the ongoing Star Trek saga and the Defiant spin off series! As emperor of the Klingon Empire, Kahless II has consolidated power, raided ancient tombs and secret bunkers, taken the power of gods for himself, stolen the Bajoran Orb of Destruction, and has begun a slaughter across the stars. But this genocide of gods was just the beginning. For with the power he has stolen, Kahless is about to declare war on all those who do not follow the Red Path. To prevent genocide unlike any since the ancient days of Qo'noS, the crew of icons led by the emissary known as Benjamin Sisko and the renegades who follow a desperate and violent Worf must unite for a common cause. Only they can hope to stop the Day of Blood.
