Thule

The island of Thule was a rocky atoll and the subject of much mysticism and conspiracy in the Wizarding world. Thought by many secretive organizations(such as the Thule Society, which was named after the isle) to be the birthplace of magic and Wizard-kind, the island was lost soon after its supposed discovery by the Greek wizard Pytheas and was not rediscovered over two thousand years later by Ruprecht Totenkopf.

However, in the battle that ensued on the island, Thule was destroyed and sunk forever into the depths of the Atlantic Ocean.
