I do not know if the omake was cannon but More'lumix hates Turoq for cheating her out of demonhood. So I do not see Turoq going to her. Maybe packing up and running.Alright, agreed. Jacob is mainly a hero killer anyways, and we've got plenty of those on Muspelheim as is between Surt, Jane, Horatius, and Julius Muspelheim has plenty of those.
More likely I think he'd supplicate himself to More'lumix, with the tech as his offering for why she should bother. Being someone else's subordinate would suck, but he wouldn't be dead, he'd probably be a favored subordinate anyways, and he's pragmatic enough that he'd likely be willing to go through with it.
