One day, the inhabitants of the world of Alconar will learn about the existence of an alien race of people on it. People who had previously lived in isolation become the main link that turned the tide of the long war between elves and orcs. By the will of the prophecy, people summon demons to Alconar that were expelled from the planet five hundred years ago. Now, people, elves, orcs and other races inhabiting Alconar must survive the onslaught of demons and find the strength to defeat them. Otherwise, the world of Alconar, as it has been all these years, will come to an end.
