Okay, here's my dilemna...
I'm in Marten's Bluff and I've already attacked some of the T'Rang so I'm not exactly on their good list right now. That's fine... it's kind of fun watching them quiver in fear as my party takes them out.

Anyway, I fell through the floor, ended up in some water, and am now walking around and trying to figure out what to do. I see a catapult, but selecting it doesn't do anything so I assume I need something to operate it... fine. I took an elevator downstairs and got into a fight with Z'Ant. Now that he's gone, I see a door which obviously requires a handprint that my party does not have (I made a Lizardman fighter instead of a T'Rang one... oops)

I've walked around this area time and time again but I cannot find a T'Rang hand to use. Do I need to walk back out to the Swamp and re-enter Marten's Bluff via the mine shaft to find this hand that I need?
Feel free to spoil me, I don't mind...
