Caspian and Elincia have completed their mission in Dorumhold. The slave-trading operation has been wiped out and the Sorceress charged with ruling put back in place. Now, all that’s left is for them to return to Casadinia and report on their success. Or so they believe. But the danger isn’t over yet. In fact, it is just beginning. And it all starts when they return to Casadinia and find out that Sylvia is being charged with treason.

Caspian has confronted his past, become stronger both mentally and physically, and defeated the Lich King, Fragarach, thus laying his undead mother to rest. But while Lich King threat has been resolved, another one has cropped up in the port city—Dorumhold. The governing noble of the city is suspected of trafficking slaves. Sylvia has requested Caspian and Elincia to look into these allegations and, if proven true, bring the noble in question to justice. What seems like a simple task on the surface proves to be anything but as Elincia and Caspian find themselves contending with something they never expected to before. Another Sorceress, one not beholden to the Sorceress Council.

Caspian, Elincia, and their companions are on the run. They’ve made it to Fas Sheras thanks to Dranor—the Elf whom Caspian and Erica fought so long ago—but that doesn’t mean their troubles are over. Something strange is happening beyond the forest’s border. Cleopatra is acting unusual, dark figures are moving about in the shadows, and even the Elves seem divisive on what to do about Caspian, Elincia, and those who came with them. The true enemy is on their doorstep, but no one even realizes it…

It’s been several months since Caspian became Elincia’s knight. Their work hasn’t been too difficult thus far, but that is about to change when Sylvia tasks them with settling a dispute between two MagiTech companies: Thaumaturgical Industries and Harmonix. What should have been a simple investigation regarding the buying, selling, and creation of magical matrices becomes so much more when Cassadinia is attacked by Murakumos—the powerful MagiTech automatons that devastated the Colosseum during the Sorceress’s Knight’s Tournament. Discovering who is behind these attacks will take all the wit and skill these two possess. But they may not like what happens when they discover who the culprit is.

Having nearly let Elincia die after they were attacked by a squadron of magical machines, Caspian is determined to become even stronger than he is now. But there are a lot of things standing in his way. The tournament is still ongoing, and with several people plotting behind the scenes, it will take everything he has and more to protect his friend and emerge the victor from the Sorceress’ Knight’s Tournament!

Arcadia's Knight Academy is the premier school for young men hoping to become a Sorceress’s Knight. Only nobles, people with power and prestige, are allowed within these hallowed grounds—which explains why Caspian Ignis del Sol is hated by everyone. He's not a noble, or of even slightly noble lineage. As payment for being enrolled in the academy, Caspian is sometimes given tasks to perform that take him outside of the academy walls. This time, his job is to deliver a letter to a Sorceress living in Ashtown, but when the train that he’s riding on is attacked by a mysterious band of thugs in cloaks, he’ll find that there is a whole lot more to this quest than he first imagined.

Caspian has made contact with the sorceress who resides in Ashtown, but Erica Demonica de Angelo is nothing like he expected. Arrogant. Narcissistic. Rude. She is everything that he despises, and now he's being forced to protect her. With disaster waiting around every corner, a clumsy but cute maid, a masochistic knight, the threat from an assassin looming over his head, and, of course, Erica herself, Caspian will need to hone all of his skill, strength, and wit if he wants to survive this precarious situation alive and sane.

The Sorceress’s Knight Tournament, a competition that’s hosted once every five years, has come to Arcadia’s Knight Academy. This tournament will decide who becomes the knight for the newest sorceress—who just so happens to be Caspian’s childhood friend.

Caspian and Elincia are sent to investigate rumors of a necromancer raising the dead near Parume, Caspian's hometown and a place that holds many unpleasant memories for him. What started as a simple investigation soon becomes much more when Caspian and Elincia are informed that what's been raising the dead isn't a necromancer but a Lich King, the highest and most powerful class of undead monster in the entire world. Now they have to travel around the area, to see how far the corruption has spread and save anyone who is still alive. With their lives and the lives of everyone in Arcadia at stake, Caspian and Elincia will be forced to push themselves to limit if they wish to avoid a fate worse than death.

Caspian Ignis del Sol, a knight in training, finds himself in over his head when he becomes the temporary protector of a sorceress who's been given the nickname "Succubus."
