Calgonian Realm

Casey Callow, a prestigious member of the Protection Guild, has her sights set on understanding the rare power over darkness plaguing her country of Calgonia. In a land where everyone possesses an ability over either water, air, earth, or fire, darkness stands out as a dangerous and mysterious fifth element. But darkness is not the only thing plaguing the country. Rival to her own guild, the Assassin Guild poses threats to Calgonia with their less than moral undertakings. After the estate of the esteemed Onendilo family is ravaged by darkness, Casey soon discovers the Assassin Guild is more sinister than she once believed. She finds herself partnered with the enigmatic ex-Assassin, Noriko Ondendilo, as she works to uncover the truth of the Assassin Guild and its connection to darkness. Through trials of trust, love, and humanity, Casey and Noriko strive to save those closest to them from falling into the clutches of the Assassin Guild. Can the duo uncover the plot of the Assassins in time? Or will the Assassins' use of darkness consume all they know to be true?

The Mercenaries of Ice and Shadow have but one goal: aid those facing peril, no matter the cost. Years after the Assassin Guild War, the Mercenaries, led by Casey and Noriko, continue to focus on helping those possessing the power of darkness. Though the power is no longer as rare as it once was, those possessing it are no less persecuted and discriminated against. Attacks, disappearances, and even murders have become part of normal life for people with dark power. The Mercenaries stand as their one unfailing ally. When the Mercenaries find themselves targeted by the most obstinate anti-darkness organization, Casey and Noriko must journey to uncover the truth behind the persecution. Through unlikely allies and twisted battles, the duo discover how deep the pain of those possessing darkness runs. Will Casey and Noriko be able to find the source of the persecution in time? Or will the power of darkness die out with all those who possess it?
