The Than-Thre-Kull are a highly intelligent insectoid race in the Systems Commonwealth of the Andromeda Universe.
Beginning on their homeworld San-Ska-Re, they are the only race to have developed Slipstream technology independently of the Vedrans, and had already expanded onto nearly one hundred worlds when they encountered and joined the Commonwealth.
After the Fall of the Commonwealth, the Than were one of the few societies to remain relatively unscathed. They fell back to the security of their home systems, and continued to exist in much the same way they had before joining the Commonwealth.
