Karturan

The Karturan were a humanoid species of conquerors.

Technology
Karturan stormtroopers wore heavy, silver, power armour. They had distinctive helmets with turquoise crests and  thin eyeslits, revealing glowing eyes. They had bulky weapons that shot needles at hypersonic speeds. They also had energy weapons that could cut through walls. For flags they used telescoping rods with a holographic symbol.

Culture
Karturans were natural soldiers and had no remorse. When they came to a new place they tried to conquer it, systematically spreading out to kill the inhabitants. They were organised into the Karturan Congruity. The leaders of the Karturans could be identified by their white crest. They were trained to use objects in the environment to make tools.

History
Seven Karturans were brought to floor 140 of the Edifice. They conquered the floor for the glory of Kartur, then moved up to the next floor, killing the residents along the way. (NSA: The Forever Trap)
