Pfalz island is a small fortification in the middle of the Rhine that sits roughly 39 miles downstream from Bingen. It functions as a toll station for traffic on the Rhine river and all river traffic must either stop there or in the town of Kaub to pay. At one point it was the covenant of Rudaria. the magi living there had an arrangement with the Landgraf of Rudesheim. The magi and all the inhabitants of the island disappeared under strange circumstances. Since the covenant itself was never recognized by the Tribunal, no formal investigation was ever launched into what happened to the covenant.
