The mythical realm of Hyperborea was ruled by an ancient civilization that used magical crystals as their main source of energy. With time, the Hyperboreans became greedy, and their search for power in the deep made the crystals unstable, causing earthquakes, mutations, droughts and floods. Hyperboreans just dug deeper, and only a few wise mages, foreseeing the inevitable, built an unbreakable magical barrier. When the unharnessed magical energy was unleashed from the deep, the Hyperborean civilization was destroyed in a single day, only the magical barrier preventing the disappearance of life from the whole land. The survivors living in the small outposts outside Hyperborea were now sealed out by the barrier. The knowledge of crystals was declared forbidden it was because too dangerous, or simply forgotten.
