One possible topic for discussion is little things in canon that might inspire people to write stories, since we won't receive more from Minna. I was thinking about Onni today, and it occurred to me that there's something odd about his story that I don't recall anyone pointing out. Why wasn't he with the hunters and scouts in Fall Y79? Why was he on the island of livestock and crops?
two things:
Now this may be just my head cannon, but what little I inferred from the comic, Onni was responsible for Turri. The part we saw in the comic (Adv II) is Ensi pecking on Onni saying "I gave you one job!" Maybe Ensi had some premonition that Tuuri was going to die young, and that Onni was supposed to prevent it (You can go into a rathole about "fate"and all that here)
The other is that I believe Ensi was not happy with Onni. He is a different person than Ensi. I felt his magic was more spiritual than physical. Whereas Lalli and Ensi were more of the physical.
The other thing (this is strictly head cannon speaking) I think Ensi was either "date-raped" , drunk or did so, thinking she would not get pregnant. The interactions with her sons seemed less than warm.
It's not because he was too young; Lalli was there and he was eight. It wasn't because he wasn't immune; Hilja, Tapsa, and Ilmari were all there and they weren't immune either. In Y90 he was paralyzed with fear of the outside, but he clearly wasn't in Y79, since he travelled from island to island with only his little sister. So why wasn't he with the hunters and scouts?
I think the fear is how everyone died so quickly and by one of their own. I think Onni, Lalli ad Tuuri all had a form of PTSD from the incident. Especially since they were the only survivors. (Survivor remorse?)
Also with regard to Onni, why was he so completely ineffective against the Kade? Breaking the fourth wall, I think Minna was tired of the whole thing, hadn't worked out how he was going to defeat the Kade, and just threw in a deus ex machina, but if you want to make the canon make sense, there must be some reason why he was totally wrong about his abilities.
I don't think he was. Onni seemed to be more of a mental mage than a physical one. Lalli was more physical, was able to search the physical world for trolls , safe paths and even weather. I think though the addition of Reynir (Not so much Lalli), brought a different form of magic. Part of my head cannon is Reynir can be like a spiritual guide. He did that with the ghosts in Denmark, why wouldn't that talent extend to the trapped souls of the kade.
I really think Reynir is special or his magic is. All of the Icelandic mages in the comic were female. Given their power from Freya.(according to some mythos).
So Reynir is either blessed by Freya, (through some if the readings I have done, is gay).
Or he is blessed by Odin and would be very powerful indeed.
From what I read, Icelandic male mages were special.
