I saw that and went OOOOOOOOOOOOO at the possibilities of what family members attempting to reach an infected person's soul might mean. Finnish witches' one big specialty is fetching souls that have disappeared after all. Usually the itse-soul, occasionally the luonto if it can't find its way back. (Henki though, when that's gone the game's over, no one can get a henki back once it's gone.)

While henki is your life force and luonto is your protector and luck, the itse is your personality, literally your self. The info page we just got gives symptoms that, to a Finish mage, might well look similar to the condition of losing one's itse. Might some mage have been desperate enough to try to go fetch the doomed soul from the underworld?
