My story is called "Split of the Worlds" (original "Weltenbruch" in German). It's referring to the fact that the world of the protagonists is broken apart, in more than one way.
When humankind was growing, some of the angels were fascinated by the darker emotions some humans beared. And how it sometimes is, great power leads to bad effects, so the Mother (the goddess, so to speak) split the realm of the angels apart from that of the humans, to try to protect them. And to protect the angels in the new dimension from further corruption She also seperated the angels and the now formed demons. The White Mountain and the Red Depths can only reach each other at certain times, the closures, when their parts of their world swing back together.
The ways of life of angels and demons are quite different now, and of course both ways are different from the human lifes.
So we have a lot of splits in the world(s) in my story, physical, cultural, spiritual.
Hence the title.
