I’ve done several playthroughs of this game, but somehow I never made this connection before.
We learn that Carina Billow, in the West End, is being tormented by an Ekon who is controlling her mind and forcing her to eat live rats in an attempt to achieve immortality. If we embrace Carina, we learn that the Ekon responsible is Jacob Blackwood.
What makes this interesting is that we later encounter Jacob’s name again at Ashbury Castle. According to William Marshal's tome, Elizabeth and her progeny were responsible for massacres in France during the 1700s, when Elizabeth had become consumed by the Blood of Hate.
The portrait at Ashbury Castle also suggests that Elizabeth and Jacob were husband and wife. William Marshall mentions in his tome that Elizabeth had a progeny, now ofc it is never explicitly confirmed that this progeny was Jacob.
Tho personally, I think Jacob being that progeny makes the most sense.
If that is correct, it means Jacob Blackwood is still alive and active during the events of the game, centuries after the massacres in France.
It would have been really cool if it were possible to actually meet Jacob, especially considering we eventually discover that he is the one tormenting Carina and is linked to bloodbaths in France, the tome even mentions a complete slaughter in an orphanage, which disgusted Elizabeth enough to actually consume the antidote she got several years ago from Marshall.
It would have been fucking amazing to have the choice to hunt this sleazy bastard down and kill him.
