The First Spark

For as long as the races of Clestroia could recall walking the surface, so do they remember the Beasts. Monsters that roam the land, making every day behind even thick walls someone's last. The only truly safe places are the Bastions - towering cities standing upon massive pillars and stretching kilometers into the sky, above the monstrous horde and ever-changing borders below.
However, in a world constantly on the brink of war, a single spark will be all it takes to burn everything, and when Arcturus stumbles across an egg containing the most powerful Beast of all, he finds himself in the middle of events that will make him questions who the real monsters are, and whether or not he should fight to preserve the way things are from the oncoming blaze.
