Biography
Juras was the conceptual designer of the motherships that were launched to explore the galaxy in the Golden Age of Expansion. While the motherships bore his design, the Templar Caste, against his objections, installed weapons systems on them, even converting some of the vessels to lead armadas. Juras was still allowed to keep his prototype ship, the Moratun, for exploration however.
