oops, sorry i posted the links.

anyway my post said:

there's discussions in the fanfics forum where players have discussed their backstories. the tencent developers have also come up with backstories for the mains in the og cn game and you can find them on baidu (china's wikipedia/google-like site).

i can PM you the links but i'm not allowed to post them here. The articles are in chinese, so use google translate at your own risk.
