There is more to the dahl than just technology, and science.
They are a race pf hard working, honest creatures that will do their job and do it well.
Though the dahl may not have as much cultural aspects as we humans, but they have one none the less. They celebrate holidays and live lifes day to day until they are put to work by their government.
The dahl are a militarized race. They have advanced weaponry and tech, but this is cause they over compensate for the dangers that they may fine or stumble upon when exploring the stars. They may be militarized, but their sole purpose for reaching out to space is solemnly to explore the distant stars, and to find sentient life like themselves and also expand their knolage.
The dahl keep their population at a ateady five billion dahl. The way the dahl reproduce is through artificial reproduction. They use special facilities to produce young.
They believe natural breeding is horrid and wrong, and may get their population numbers out hand.
A neat thing the dahl do is that they take their dead and dying, and make them into special creatures they call BioSynths. Which are basically revived, or saved dahl with life support equipment melded into their bodies
Thats all i got for now.
