The Perry Rhodan cosmology mostly consists of the struggle between the Powers of Order and Chaos. The most powerful entities known of each side are the Cosmocrats and the Chaotarchs.
Their genesis is outlined below, using the so-called onion layer model.
The onion-layer model is a model of the evolution of intelligence in the Perry-Rhodan-universe. Thinking about an onion, the innermost layers represent the primordial matter. Nearer to the first layer, there come primitive life forms, such as bacteria, then animals and then intelligent races that have not yet left their home planet. Interplanetar space travel is the next step, then interstellar, and up to intergalactic space travel. Interuniversal travel is rare. The next step is becoming a super-intelligence.
A super-intelligence is often a bodyless being of pure thought that is created from the minds of whole races, controlling several galaxies. These galaxies form the power center(translation?) of the super-intelligence. The primary measure for the power of a super-intelligence, however, is the amount of knowledge and wisdom it has achieved. This allows them to extrapolate current events to almost accurately predict the future.
Super-intelligences are classified as being either positive or negative. This has nothing to do with good or evil, however: Positive super-intelligences form almost symbiotic relationships with the races in their power center, while negative super-intelligences exploit them in a parasitic manner. Ultimately, a super-intellience is drawn to the next layer of the onion. They concentrate the galaxies of their power center into a small spot and merge with them into a matter spring if they are positive, or a matter sink if they are negative.

The niveau of matter spring/matter sink is the highest niveau of intelligence that is known in the universe (Cosmocrats and Chaotarch are entities of the multiverse), created in a process similar to the creation of a Black Hole. Few things are known about the workings of these entities. The matter springs create matter with unknown means and "spread it out" in the universe, while the matter sinks are purely destructive: They do not return anything to the universe.
After an unknown span of time, the Matter Springs evolve into beings that, lacking a better word, are called Cosmocrats, while the Matter Sinks evolve into Chaotarchs.
AFAIK, only one Matter Sink and one Matter Spring are commonly known, JARMINTHARA, the Matter Sink, and GOURDEL, the Matter Spring. Both of them can be found in the galaxy Erranternohre, where they have gone due to commands from their respective sides during a battle between Order and Chaos in a nearby galaxy about 3 million years ago.

Cosmocrats and Chaotarchs are the most powerful known entities of their respective side, as I have already said. Cosmocrats are said to live "beyond the Matter Springs", whatever this may mean. Their mentality and their goals are virtually inscrutable to mortals, except that they try to influence the Moral Code (which can be said to be some kind of genetic code of the Multiverse), just like their counterparts do. The Cosmocrats apparently strive to achieve some kind of Order and keep it up for all time, while the Chaotarchs want to spread Chaos.
Both Cosmocrats and Chaotarchs act mostly through servants, though on rare occasions, one does manifest it's will within a universe. Known Cosmocratic
servants are the Knights of the Deep, the Servants of Matter, the Seven Mighty Ones with their Spore Ships and the Swarms.
Few Chaotarchic servants are known. The known ones are the Architects, the enigmatic Dark Birthes and the now-destroyed Decalog of Elements, which had it's home in the so-called Negasphere, a place that was in a constant state of "decay" due to a manipulation of the Moral Code.
