Xak III: The Eternal Recurrence

Xak III: The Eternal Recurrence or Xak III (サークIII) is the final game in a fantasy role-playing video game series called Xak developed and published by the Japanese software developers Micro Cabin and NEC. Xak III was originally under development to be released for the MSX2 but shortly after Xak: The Tower of Gazzel was released, the development project was halted. After several years the project was continued and finally released simultaneously for the NEC PC-9801 and FM Towns. A year later, Xak III was released for the PC Engine Super CD-ROM²; this version has since been unofficially translated into English.

Plot
Xak features a typical high fantasy setting. According to the game world's legends, a great war was fought between the benevolent but weakening ancient gods and a demon race, which led to the collapse and eventual mortality of the gods. After this 'War of Sealing', the gods divided the world into three parts: Xak, the world of humans, Oceanity, the world of faeries, and Xexis, the world of demons. The demon world of Xexis was tightly sealed from the other two worlds as to prevent reentry of the warmongering demon race. Some demons were left behind in Xak, however, and others managed to discover a separate means to enter Xak from Xexis anyway.

At this point in the series the main hero, Latok Kart, has become a powerful adversary against the demons and their plots to conquer the world of Xak as he has triumphed over many powerful demons, including Zemu Badu, Zamu Gospel, Zegraya and Gazzel. Latok is a direct descendant of an ancient god of war, Duel, and his deeds have since become well known throughout the world of Xak as the legendary "Duel Knight", armed with a powerful relic known as the "Xak Sword". During this time a short-lived peace has been disrupted by the sudden attack of the nearby Kingdom of Farland led by a demon named Zomu Dizae. Latok learns of this and sets out for the Kingdom of Farland.
