Matras:
Actually, I need a blueprint of the structure of the tower of the Steel Citadel. I have learned who possesses the information I need, but I can't get it on my own. Perhaps...someone like you could go into the tower, find that blueprint and bring it to me. Apparently the Demon Prince and Ranku in the Steel Citadel have access to the blueprint I need. Please bring the blueprint to me, and I'll reward you very well.
Oh, one last thing: take these raw ore. They might look rough, but they function just like other ore. I think they will help you in this task.
