Soooooo we ended up getting the "No resolution" ending. We had Silas dead to rights, but drew the wrong chaos token and pulled an ancient evils with no ward in hand for an extra two doom tokens that left us without enough actions to win.
Couldn't win before doom ran out and decide just to get to safe spots and spam Delve Too Deep and get something for our troubles.
Just to confirm with the no resolution we don't get the interlude and don't get the Powder of Ibn-Gazi, correct?
