Comment by HaDoSh on PRIMORDIAL THE ONE

@BLACK PRIMORDIAL NOIR   Both the MCs that I mentioned are Koreans. One is from  The Legendary Spearman returns and the other on is about a third prince that had his kingdom annihilated by the empire and he regressed and started changing things.  There is probably a third one about constellations and outer gods but I can't remember the name.
