Barracuda's Sonstiges Self

There was a letter attached to the Anvil. Apparently all my friends have fallen prey to the evil sword Barracuda. Yes, Barracuda. That's the name of the evil sword I made. It is a terrifying item, born out of a curse, gaining its own intelligence and killing other living things. I attempted to destroy it once, but I failed and lost all my Colleagues. We were all so happy to find a tool to help destroy Barracuda, but now I'm the only one left and according to this letter two more powerful tools were taken by the monsters controlled by Barracuda. We need to find them. According to what the letter says, Queasa Soldiers took something called the Grindstone of Origin. We need to retrieve it. The Queasa Soldiers frequently gather at the Giant's Highroad. Get the Grindstone of Origin from them!

Help me please. Destroy the Queasa Soldiers at the Giant's Highroad and retrieve the Grindstone of Origin!

Good job. Fortunately, it's not damaged, but we need to find the other tool. That will be a tremendously difficult quest.
