So what happens to Karchev?

[CrimsonGuard]

I can't find fluff-spoilers anywhere and I'm really curious!

[Steamwitch]

in the end of tne wrath book denny janks out karchev and cryx takes the life support from his body to keep him alive. After reading the new nq i think he is undead not life supported. And thats why cryx wants him but old witch is gonna call in her favor of denny and get karchev back.
