The Key of Civilisation: The Character of the People
It is the character of the people that makes or breaks a civilisation.
Any world can obtain tech eventually. What they do with it is what matters.
A dark world like Terra is going to use it to destroy everyone and everything. They do not deserve to have tech.
It starts with the Ruler, though - She is the one who shapes the local civilisation. And yes, it is Cosmic Law and Order for the Ruler to be a woman. It is illegal for males to be allowed in any positions of power, because they always abuse it. No sane world allows them in any position of power. They are the ones who try to corrupt everything.
A world of White Light is always white, fair, honest, disciplined. Intelligent, with good manners, work smart + hard to achieve their goals. They are never vulgar and promiscuous, nor greedy in any way.
They are not lazy either. They understand that they must work and that the success of their civilisation depends on each of them working to preserve civilisation, which includes the set of laws that NEVER change.
Truth is forever (permanent). Good laws are forever. It is the bad ones of the dark worlds that keep changing because criminals are in positions of ''power'' (weakness). Criminals make laws to prevent their crimes from being exposed or to prevent their own punishment. Which is an epic fail- without law and order, any civilisation is doom to fail. No one can thrive is the chaos criminals create.
Whenever dark souls appear in a world and prevail in numbers, that world is doom to fall into darkness unless the Ruler + the Royal Council step in to prevent that from happening. Ultimately, all the local power belongs to the Ruler.
Worship White Light, be ruled by it.
Worship darkness, be ruled by it.
It is LAW. This is how Cosmic Order works.
When one worships criminals, they are ruled by it.
There is NOTHING to love about dark souls = criminals, evil. The dead do not deserve love. You cannot love darkness = death (what kills you).
They are the problem. And when they are in large numbers, they become a threat to the entire civilisation.
Note: any sane world is unified, speaks one language, has zero criminals. No poverty, theft, unemployment, etc. But then there no species of darkness there :))))
White Light and darkness cannot coexist.
