According to legend, the magical civilization of Atlantis attained its great prosperity from knowing how to create a material called Oriharukon. Naturally, many other nations asked and even begged for this information to be shared. Rather than granting these requests, the Atlantians reacted by closing their society to all outsiders. Anyone foolish enough to persevere was dealt with swiftly and harshly, by sheer force. In time, however, the entire supply of the four crystals required to formulate the substance were exhausted. Destructive campaigns were quickly mounted to conquer the rest of the world in the desperate hope of finding more.
