Being the only child to the Queen of Castle Grey, lost within the confines of mount Trenon, Kilvic is made to learn a number of things best suited to the heir to the Elzcrid bloodline at the hands of tutors handpicked by his mother. However, his fifteenth birthday sends him beyond the reaches of his mother’s domain. She has tasked him with the duty of learning more. Understanding greater things than she can teach him, greater things with which to cope with the curse upon his bloodline as she had been taught by her father and mother. Finding himself in a new kingdom, in an academy designed for only the most elite of mages, Kilvic is tasked to survive the new things he will come to learn, while struggling with the chaos of human association, as he comes to understand that while he may know a great deal about the world from the castle archives, it is a different thing to experience them. The association between people isn’t as easily deciphered as the books made them seem. As he struggles with the task of becoming a mage and a student along with surviving new friendships, failure threatens him at every turn and people prove pettier than the books would have him believe. Yet, despite all these, somewhere hidden in the shadows of the kingdom, a creature stirs, taking from the academy the one thing it values most. Kilvic must survive the trials of the academy, keep his friends, best his first enemy, and ensure that what stirs must not cause more damage than the kingdom can bear, lest the supremacy of Castle Grey be called into question in realms beyond that which most know. And all in time to attend the Winter Hall Fest.

Evy was a simple-minded girl. If there's work she's there. Evy is a known workaholic. She works day and night, dedicating each of her waking hours to her jobs and making sure that she reaches the deadline. On the day of her birthday, her body gave up and she died alone from exhaustion. Upon receiving the chance of a new life, she was reincarnated as the daughter of the Duke of Polvaros and acquired the prose of living a comfortable life ahead of her. Only she doesn't want that. She wants to work. Even if it's being a maid, a hired killer, or an adventurer. She will do it. The only thing wrong with Evy is that she has no concept of reincarnation or being isekaid. In her head, she was kidnapped to a faraway land… stranded in a place far away from Japan. So she has to learn things as she goes with as little knowledge as anyone else. Having no sense of ever knowing that she was living in fantasy nor knowing the destruction that lies ahead in the future. Evy will do her best to live the life she wanted and surprise a couple of people on the way. Unbeknownst to her, all her actions will make a ripple. Whether they be for the better or worse.... Evy has no clue.
