There is so much interesting speculation! It’s so fun to read
All this discussion about the Kade makes me wonder if It would be willing, or bother to possess someone other than the Hotakainens in order to get closer to either Lalli or Onni? Would It even be able to, considering that none of the other characters are Finnish mages? Because the info pages only mention the Kade absorbing the souls of mages, not people in general. (But imagine how tense it would be for the reader to see a repeat of Possessed!Ensi trying to get Lalli to look her in the eyes, but with a possessed Emil/Reynir/Sigrun/Mikkel instead, and Lalli actually falling for it!)
Or would It just ignore all the other characters if either of the Hotakainens were in the vicinity and just go straight for the two of them?
Also, the top comment of
page 177 mentions that the Kade was probably attacking the familiars of the sparrow sentinel mage (Kauko Katainen) at the beginning of Adventure 2. I wonder if at some point the cast makes their way southwest, only to encounter Kauko and see that his familiars seem to be acting strangely or missing entirely
