Trion Worlds has announced the name and a small bit of lore behind Defiance's next DLD. Called "The 7th Legion", the DLC will spotlight the soldiers of the 7th Legion and their heroic arrival in Paradise.
When the world fell apart, one group kept their courage. Guided by the teachings of the Code of Bushido, the soldiers of the 7th Legion marched across Canada gathering survivors as they went. From one outpost to another they marched until finally they found a city which did not fall: Manhattan. There, they made their stand against the darkness, and Commander Yoshida Hiro called an end to their long journey. Now they have come to Paradise. What dread news could this herald?
