Daggers of the merchant Veyna

The daggers have been going off with a bang lately. They are bought mainly by treasure seekers heading to the Tower of Chaos. They are heading somewhere, but they don't come out again. Meanwhile, the demand for daggers does not end. Maybe you'll go to the Tower and take my blades away from the monsters that defeated the would-be heroes? And I'll sell them to the new daredevils.
