********!!!!!!!!!SPOILERS!!!!!!!!!!!!***********
When you arrive in Verahansha, you will make your way through the Timpo district and come upon a broken train. You must find a gear located in the western factory ( I am sure it only shows up after Edessot inspects the train). After trying to connect it, you will need to find some tools. Go back to the inn in timpo and enter the house south of it to find a man who wants some alloy for his tools.
Return to the west factory where we got the gear, and approach the large robot. BOSS TIME!!!!
This boss hits hard. Equip your dragon teeth. You can focus on taking just him out, or focusing on using AOE's. I found it best to put everything I had into hitting the boss, and healing. I completely ignored his cronies, though some of my characters died.
