“I can’t believe my eyes. The ice lord actually kissed a man. God, help me!”

There are a lot of things wrong with Liv Brodbeck. She’s too small, for one thing. When she works in the castle kitchens with her mother, she can’t carry a sack of flour or roll a keg of ale. Baron Summerset’s chirurgeon says that she has brittle bones, so she isn’t allowed to wrestle or sword fight with the other children. Even sledding downhill in the winter brings the risk of breaking an arm or a leg if she falls. Everyone says that she ruined her mother’s life when she was born. Not when they think Liv is in the room, of course, but she overhears all the same. In the kitchen of a less kind lord, a cook bearing a bastard child would have been more than cause enough for both of them to be out on the street. No, a child like Liv doesn’t have much hope. But when she accidentally unleashes a surge of wild magic, she takes her first step on a journey which will lead her from the kitchens of Castle Whitehill, to the cold palaces of the Eld, and beyond, to the graves of gods... What to Expect: - MC starts off very weak, with a lot disadvantages - not just physically weak, but also vulnerable in a socio-economic sense. She has talents, but it is going to take time to develop them. I want to give this process room to breathe, so I hope you enjoy long-term progression. - The MC begins the story as a child. As she grows up, she will have relationships that I intend to be appropriate for her stages of life, BUT THERE WILL BE NO SEXUAL RELATIONSHIPS UNTIL SHE IS AN ADULT. Expect eventual teenage drama progressing into more adult relationships. - There is action, but it is not constant action, and it will again be appropriate for the MCs development. As a child, she will be challenged by child things, and as she grows into power the scale of threats will increase.

「 I do not mind whether it is a woman in the town or a maid in our house, learn about women.」

Having gained the permission of his father, he uses his power as a noble to have his way with women.
