NobodysHome, watch out for that wife of yours. she has a mad evil genius mind! I love the idea of the captured Tangletooth and a coerced Gogmurt. maybe he will send a Birdcruncher goblin for more goblin tribes to help.
I forgot to mention I have another fun/interesting dynamic brewing in the form of Orik and Lyri. the PCs originally payed Orik to leave but instead he went and found Lyri and tried to get her to leave with him. That not working he joined up with her. When the PCs arrived and discovered the betrayal they tossed grenades in the room but in the process let slip that Tsuto was dead. Lyri, distraught escaped through the secret door but left Orik to be blown up by the grenade. the betrayal of Lyri did not sit well and the PCs convinced Orik to join them to exact revenge on Lyri.
all of this is now shaping up to be another good adventure not just a mop up of what they missed the first time. thanks for the good ideas and keep' em coming if you got more :D
