From the back cover (translated by Google):
Alphatia, the oldest empire, with ancient and mystical secrets. Empire has grown for centuries and now its power threatens all humanity. There are those who say that the Alpheans come from another world, but no one knows for sure. Beyond the reach of mortals, lies an evil genius, still in darkness. A former emperor of ancient Alphatia, and now an entity from the Anthropological Count, is seeking revenge for the greatest empire of all and the entire human race. His scheme brought a deadly mist hovering over Norwald's entire face. It may even spread to the southern nations. The situation is so grave that the Sefirot are now forced to examine their power. For them, this is the time for mortals to intervene. In order to receive divine help, one must stand on his own. A huge fleet was recruited and they were looking for talented commanders. Prove your value and the gates of eternal Sefirot will open to you.
