Coming with fog

My first memory is a fog, teeming with monsters. I don’t remember anyone, nor how it turned out here, but for some strange reason the monsters do not touch me. Learning that I came with the fog, some are eager to burn me like a witch, others protect me. The king’s adviser sends him as a spy in the Nergard Castle to monitor the sorcerer that is objectionable to him. And at first it seems quite sweet. But they all hide something, and I will have to figure out who the good guy is, and who is bad, how they are connected with each other, and what I have and what I did not immediately please the head of the Nergard of the Guardian. And only one random acquaintance is exactly on my side, although he does not know me at all
