A DEMON WITHIN. AN UNKNOWN ENEMY. A DEADLY THREAT. Gothalia Ignatius-Valdis, burdened by a curse and shrouded in animosity, possesses the potential to become the greatest asset to her homeland. Within the clandestine subterranean country of the Fire Reserve, a subterranean city known as New Icarus thrives, housing extraordinary beings known as Excelians who wield superhuman abilities and command the elements. Unfortunately, Gothalia's ill-fated existence stems from her inheritance of unstable élanocytes, known as délanocytes, a genetic trait passed down from the Valdis clan, rendering her an outcast from birth. Unexpectedly, the Grand Elders decree her compulsory enlistment into the military, specifically the esteemed Centurion division. It is here that she encounters the heir of the Nero-Drausus Clans and the Crown Prince, forming an unlikely trio of companions. The Centurions, the Fire Reserve's vanguard and final bastion of defence, face a perilous existence, with their life expectancy significantly lower than that of the average Excelian. As the tranquillity of their homeland teeters on the brink of destruction, Gothalia finds herself compelled to take action. Yet, a lingering question haunts her thoughts: Will she choose to aid those who have caused her so much pain and suffering?
