After the trolls the pcs explored the gate house. Then they cunningly lured the flesh golem hound to the portcullis and Hadhod grabbed its paws while Gregor cut them off. The golem-hound stumbled off the bridge and into the chasm. Then the pcs crossed the bridge and entered the large living space keep. In the first room they battled a small bladed iron golem. There was a long stalemate as Gregor was unable to hurt the golem and golem was unable to get past Gregor's shield.
But eventually the pcs found weak spots and disabled the golem. The pcs found Caromarc's secret treasure compartment but other than the golem the main keep was empty. Then the pcs crossed the next bridge to the laboratory keep. A large explosion had damaged it and it appeared unsafe. Gregor was then attacked by a pair of rust monsters.
His armor was damaged and his mundane sword was almost destroyed before the beasts were slain. Then the Hadhod attempted to cross a rope and plank bridge. Near the midpoint of the bridge a magical trap conjured a pair of harpies with bows that fired on Hadhod while magically calling on him to fly to them. Hadhod tried but was unable to fly but he fell very well. Hadhod managed to survive the fall and the rapids but was swept far down stream.
Gregor and Glade were able to resist the siren song of the harpies long enough to send them plummeting into the abyss. At that point the pcs came face to face with the dreaded Bride. Bride told the pcs to leave and never come back or they would be slain. She then used super human strength to tear the plank bridge asunder. Gregor and Glade decided that it would be a good idea to leave and rescue Hadhod but it was approaching midnight and so they retreated to the gate keep to sleep through till dawn.
