Yang aliens are like viruses to the Night Soul of this world. They don't have homes. What we know as their home planets are actually remnants of their own destruction.

Viruses.. are not like bacteria. They are really unnecessary in the circle of life. We don't know where they come from - although it is suspected that they are remnants of soul death. If a Creature Soul undergoes soul death during incarnation, for example, its cellular body would most likely become cancerous. Its DNA strands may break up and create zombie-like organisms. That's probably where viruses originated from.

Isn't that what most of humankind is? Zombies?

Viruses can't produce energy by themselves. Nor can they reproduce. They can only do so by corrupting cells. It's exactly what Yang souls are doing to Earth and Tiamat. They rape resources of the Earth and moreover they corrupt souls in order to create more of their own. If you look at viruses and cells, they look eerily similar to what alien spaceships are like to Earth. They don't belong here.

Most cells have defensive immune systems. Likewise the Night Magicians have their own ways of defending themselves from the visitors. Earth itself has a sphere of wall that fends off aliens from directly interfering with us. Not to mention the Night races who can destroy them once they entered into our sphere of influence.

This world though... this world may already be too late. The energy that this civilization is vibrating is very much like that of the aliens. I'm afraid I'm too lost in it myself.

What went wrong?
Something went wrong.

What do the Yang races believe in really? They are really not far off from how the Yang religions are acting like on Earth. They believe they can regenerate their home planet here on Earth. They are driven by ghost ideas and cannot let go of the fact that their own World Soul is already destroyed. So they go on destroying other worlds out of jealousy and hate. And they go on making more of themselves.

They believe humankind will become great tools to this end, to their paradise on Earth. But they will only end up destroying this planet. They wouldn't know why. And they would go on to other planets for this cause. Or they could remain to wreak more havoc on Earth.

Some of them would wake up eventually from the ghost idea. They could cease reincarnating as a "Yang" alien and begin their samsara as a proper Yin soul. But as long as Souls are constantly being created, the race itself would remain. Possibly forever.
