I remember the origin story of Perfect World like this: after separating the sky and the earth, Pangu tried to fill the world with life but the creatures became dark and malevolent, and so Pangu with the powers of wind and water, purified the world and killed all living beings. Then he tried again but gave the new creatures free will. The wraiths returned from the dead and so the new creatures has to unite against them.
Now I just started playing again, after years of absence I noticed that I got a 'Perfect Chronicles' book from one of the first quest givers. In the book the origin story is completely different and complex. Pangu died, his essence became new gods who created everything, the wraiths came from a dark realm/dimension, the new gods destroyed the old world and created the perfect one.
I'm kinda lost, can someone tell me what's happened?
