Before its destruction, Atlantis blossomed into the most advanced civilization Earth had ever seen with the help of a vast energy source called Oriharukon. Under the control of Eve, a highly intelligent computer system, the Atlantians surpassed all other civilizations and invented revolutionary technology that cemented them as the new world power.
But as they stretched the energy farther and farther, the very fabric of space and time tore, wiping Atlantis from the face of the planet and leaving behind only frail memories and mysterious relics.
After 1,500 years, the city mysteriously returned. Ancient relics reawakened and Oriharukon flowed once more, driving creatures mad and sending the world into an age of chaos.
Now, with Riederan dangerously close to harnessing the power of Oriharukon, Eve hastily constructs the city of Antillia and awakens an ancient Atlantian to defend Atlantis. It's up to this Atlantian to gather a team of mercenaries strong enough to stop Riederan before he discovers Atlantis' most treacherous secrets!
