Ok, so far I think I can piece a few things together

At the end of IR, Jae really wanted to kill Serin, because he had lost his bro...
That old turd seems to have used Jae to completely annihilate the Maho Clan

Errr lets just put it like this

Jae had a thing going with Serin and is the reason why everyone fears that Jae look alike
Jae sealed Serin for her own good or to protect her... we must remember there is somekind of disease going, one that seems to turn people into tards.

I believe Miya is Serins daughter and the only reason Serin is sealed is because she is also sick, but in a much more advanced state, (Miya is so cute that I can't stop thinking she is the result of Jae + Serin) Maybe the reason Jae is exterminating all those clans and is being a bastard about it, is because he wants to Cure Serin and his Daughter, wants to keep Chaos Above the Ground, and is tightly hoping to save Chaos and get his brother back.... uff if you put it like that, I can understand him being a mother fucker and raping his way to greatness...

owke as far as i can see o3o

Jae after the whole brother thing went and learned negative magic and became full fledged bad-ass, then after kaladbolg (jae's little bro) gets freed he attacks the floating city. Jae ,who has distanced himself from selim, because he thinks she wants nothing to do with him. this is also due to the fact that the blood Selim sends to Jae get intercepted and thrown away by Depore, who is very jealouse o3o. after the attack and such Selim is hospitalised and the whole misunderstanding gets cleared up. and in a moment of love~ the two become one ( THEY F*@# ^(^o^)^ ) the rest isn't scanlated yet, but it seems Selim escaped and joined the .....forgot name those infected people. She was pregnant at the time (^(o3o)^ Go Jae) and i thinks the child that came from that was Xix cause he could open the seal that only people blood-related to Jae can open. the fact that everyone that becomes infected brings misfortune they get killed, Jae to protect the rest of his subjects he kills every single person that COULD be infected. But because he captured Selim rather then killing would probly mean she is infected and Jae just can;t get it over his heart to kill her (aaaaaaawwww~~~) and then the child miya would be the only blood-related child made between Jae and his new queen.

o3o or at least thats what i think
