This will be my race.

The Ka

The Ka is one, the Ka are many but all work towards the common goal: survival.
The Ka are a synthetic race that roam the galaxy in search of resources to fuel their ever expanding collective. Unlike other species, Ka do not have any sense of individuality or even a concept of death. Ka are essentially billions upon billions of computer programs, all working together as one. Their ships, resource gatherers and soldiers are all mobile platforms within which these programs operate.
While the processing power of the Ka collective mind is almost unfathomable, they are sadly extremely uncreative. All their ships, stations and other designs have been based off of others. Sometimes different designs are combined or improved upon after new data has been gathered but the Ka have never created even a single original design themselves.
Aside from one single permanently occupied system known as ‘the shrine’, the Ka are a mobile civilisation. Their so called ‘collectors’ travel around the galaxy in search of resources to further the expansion of the entire collective. This can be minerals to build new ships but also new technologies they can use. To this end, no holds are barred. Advanced organic civilisations, great or small are all targets to mine for resources and like everything else, to be discarded when depleted. They only make exceptions for pre space age civilisations, having learned that such creatures are better left undisturbed and uninformed until they can come up with enough ideas to steal. 

The history of the Ka is long but sadly, not much is remembered. They were created at one point in time, likely many centuries or even millennia ago by an unknown and long since vanished creator. The Ka do commemorate their creator by having a world spanning shrine in his, her, or their honour. This shrine can be considered the Ka’s homeworld and is likely the site of their creation. The planet itself is mostly covered by immense projects of Ka made artificial landscapes to mimic the world as it once was in the times of the creator. In order to maintain these artificial ecosystems, the Ka have built thousands of monitoring and maintenance stations on the planet as well as in orbit.
