Grimma lights her lantern and you proceed northwards, back to the area where Gerhard fell
(in front of #40). Oberon feels the pull to the west, past the rooms where you freed Finnr
(35/36). You stop just before an intersection - ahead to the right is a tunnel
(greyed-out area), while the one you are in continues slightly southwest. Oberon feels the pull strongly now, to the right.
Actions? The area to the east is as of yet unexplored, so don't let me railroad you if you want to go that way, I am working on the assumption Oberon wants you to face the demons and is following his instincts/sword
