Oo, interesting discussion! Interesting current events too.
I am certain the shadow thing is Surma. We saw It stirring when Mole Bear fell and Mama Bear yelled out in grief. Also Surma's claws form part of the brilliant chapter cover.
Team leadership:
I agree that the team doesn't really have a clear leadership at the moment. In theory, Lalli is the leader for everyone except Onni, because the others followed him on his mission. The mission statements are also all over the place:
- Onni wants to end the Kade and/or save Ensi
- Lalli wants to save Onni (and possibly also help him now that he more or less* knows what Onni plans)
- Emil wants to make sure Lalli doesn't die
- Mikkel probably wants to keep the kids safe and also give Onni a piece of his mind about Shenaningans (this may or may not already have happened)
- Sigrun comes with Mikkel to speed things up and make sure he comes back to Norway with her (and probably also to keep the kids safe)
- Reynir wants to Help: Help Lalli find Onni, Onni win in his mission, and keep everybody safe. And have Adventures as a Proper Mage! That is very important.
(* I think less: Lalli knows Onni intends to do something about the Kade in the Dream World but I doubt Onni has shared what it is exactly he is going to, or thinks he's going to, do).
It seems to be more or less a cascade of goals that has currently resulted for all of them trying to be done with the Kade, in order to be able to leave with all appropriate members still mostly in one piece.
I have near indefinite trust in the Power of Love, so I actually think they are also all going because that's what
families friends do. I.e. despite of what each has said aloud, the rest of them went after Lalli because they didn't even consider abandoning him. Towards the start of Adventure 2, we don't see any debating - once they learn Lalli has gone, they follow, whether for their stated reasons or just because.
Anyways, Lalli is clearly not a leader type. At least so far. When they catch up to him, Mikkel takes the lead and arranges the travel. Later, in Saimaa, it's again Mikkel who makes sure they prepare for the trip. It seems that Sigrun is making the combat-related decisions (for example to raid the settlement with the Kalmas - that was a bad call, but only because she received erroneous information) but Mikkel is managing the mission itself. Mikkel also has the best access to information as he can speak with almost everyone.
Like many of you have pointed out, Onni is definitely not in the state of mind to be a leader. I think he's a lot more powerful as a mage than Lalli could ever be, but that doesn't mean that Lalli would be useless! Lalli also has apparently unique experience from being inside another person's mind, which may prove important too.
Exorcising Ensi:
I agree that Ensi is beyond salvage in the sense that is meant on the Kade infopage where it talks about emergency exorcism. But, we still don't know what happens to the bodies of the possessed mages. So the emergency exorcism could apply to a situation where the mage's body is still viable and if it succeeded, the mage could be free and go on living. This is of course pure speculation. If it means this, then the case of releasing a mage's spirit from the Kade and letting it go to its normal death (move to Tuonela) could still be possible after a longer time. Based on what Onni bargained with the Swan, this appears to be the goal he's after in any case.
I too would love to see a proper story of the various souls within the Kade, but I'm afraid that will not be forthcoming. At least not from Minna, like Vulpes pointed out. But of course we can still hope! And imagine.
A bit of information about the Kade Minna mentioned in a stream, under cut in case someone doesn't want to know as it may or may not prove slightly spoilerific, although it's about something we have already theorized about before:
We asked Minna whether the Kade has an actual physical form, and she said it varies. It can take a more corporeal form, or it can be in a spirit form. However the spirit also exists in time and space, i.e. is in a specific location at any given time. But it "won't walk into a doorframe or anything like that". So, the black vortex we've seen definitely was the Kade, and I think the Blighthouse is the Kade as well.
