Spoilers about game main story ahead, you we're warned.
Since that lake village (I forgot the name, sorry) event thing, we've discovered that the Wraith Fever has something to do with all the shit that happened there.
Playing the game again, I realized that Bernard was the first person in Bareshade to get sick (after him there were a few others he mentioned).
When I was studying about the recipe of the Spectral Sirup, there is a line saying it has a chance to occur to those who visits graveyards and things like that and I remembered that, near Bareshade, there is that Old Crypt on the underground tunnels.
It made me think if Bernard was messing around that place (it would mean that, when you tell him about the Old Crypt, he says that he had no ideia it was there, so he would be lying) or someone from Bareshade that knows something.
I think this people probably is connected with what happen on the lake village (since the path to the Old Crypt is around there). It could be one of the occultists that spread the disease there and know is living in Bareshade, far from the eyes of Northcrest, hidden in a small-nowhere-village.
And it makes me think if the shapeshifters corrupted the royals from Northcrest, there sould be one of them from that family that was resting in the lake village.
It also reminds me of something Nameless told us once, that we already have contact with a shapeshifter and my guess is that he or she is probably from Bareshade.
What do you guys think?
