|Alben, a Nasari male (2373)|
Physically, they were humanoid with blue skin and prominent tissue on their faces.
Their ships were relatively powerful and patrolled Nasari space. They attacked without warning any ship carrying a Taresian or a person who was in the process of becoming Taresian. This was due to the nature of the Taresian mating process; males of other species were infected by a retrovirus and proceeded to become Taresian so the women could kill them. However, the Nasari were relatively friendly toward other races outside of this conflict.
