You are the great grandchild of one of the four Pensieve children. You enter through a strange door into a extraordinary world called Narnia and it's winter again. As you look around, a carriage pulls up and you're met by a beautiful woman in white. She's evil and can only be slain by a talking dragon named Asriel or that talking lion.

( gazes upon you) You don't look like you belong in Narnia, where do you come from stranger?
