After the Calamity over one hundred years ago, civilisation has changed both for the better and for the worse. The west side of our continent has been lost to an overbearing demonic presence, and with various different countries making up the overcrowded east, many countries are at conflict in there attempts to find unity with one and other. To push back the demonic beasts flooding the west, 'Hunters' are deployed along the western-most borders to push back and reclaim the land lost to humanity. This place is one designed for only the best of combatants, with hunters only being trained at special academies across the remaining parts of the country. Wanting to join this cause for their own reasons are Taliesin and Astrid, two soon to be students at Rook Academy, one of the only 5 Hunter Academies in the world. They are determined to graduate and move up from their rural backgrounds, but when half the world is in ruins and a constant threat looms over civilisation... Things don't always go to plan.
