"Before it happened the world of the mystical and the human realm were separated," Mariza replied. "There would be the occasional meetings but they were largely unseen. But then, at some point a millennia and a half ago, a human stumbled across an ancient book, written by a Persian who had conversed with the fae, and believed the fabled World Tree held the key to giving humanity true power. He raised an army of all the darkest creatures of the world and three them against the world tree. The forces of light, together with the few humans who knew the truth, stood against the army but when it became clear the Tree would fall the fae leader, my own grandmother, made the choice to destroy the World Tree."<br/><br/>"Which is why there are artefacts called Fragments of the World Tree," Lehmann said as he re-entered the room. "The amount of power held within that tree made it impossible to destroy the tree outright."
