Matras:
All you have to do is simply draw their attention and I will take care of the rest. Although now that I think it through, it would be even better if you could, uh, get rid of them.
Do so and bring me the Red Stones that they carry. No questions! I told you I would reward you well for your trouble. In fact, if you bring 744 Red Stones, I'll give you something very special. Understand? Good -- we're agreed!
Remember, all you have to do is to get rid of whoever you find on the first and second floors of the tower. Good luck!
