The Accordion Magisword belongs to Prohyas. It appears and can play like a real accordion. The sword made its debut in Dolphinominal. Prohyas played it because Phil stole the Dolphin Magisword from him. Prohyas also played it in Warriors for Hire to get the attention from the citizens of Rhyboflaven. Prohyas was also playing it in No Robots for Old Men when he and Vambre were questing on their Hoverswords and against the Pig Guards in Mystery of Loch Mess.
