Sovereign's Philosophy

The Philosophy of the Sovereigns is a collection of common ideas they share, threfore the motive under which they roam the galaxy, killing, enslaving and experimenting on various races, among which the human one.

What they believe
The Sovereigns are worshippers of the absolute power. They believe there can be a flawless species that can live forever and not have to rely on other species for survival. This belief has turned them to becoe experts in biology and genetics, especially in the fields of DNA and RNA. The elite Leeches, the "queens" of the leech hives, possess the strongest of the individuals every race has to offer. The ones possessed by the elite Leeches assume the most benefits in the society of the Intruder Alliance, and are able to command the lesser leeches and the creatures they have possessed

Zeus
Zeus, or Nihalthak in the alien language is seemingly the leader of the aliens, or at least the one with the more authority. He holds his ideals in highh esteem, and has  gone very far in his research, even as to make his possessed being virtually immune to death, apart from the brain cells. However, the body he has assumed control of has extensive intellect, therefore his brain isn't supposed to die or wither for at least two hundred more years. Nevertheless, Zeus wants to find a way to regenerate the brain cells, making himself theoretically immune to death.
