The last GM seemed perfectly fine with the idea of an undead character, as we justified exactly how she was risen that set her apart from the rest of the undead in the Lich King's demesne, and I'm just straight up migrating her from the parent roleplay thread. One of the greatest limiters is that her blood magic and her favored weapon are meant to be effective against things that bleed, and the undead just don't. The most reasonable thing I can do is justify that she is out of practice, still needs to fully reconnect with her old magic, but also mention that she never fought the Lich King directly. She definitely fought his lieutenants, but was mortally wounded before that decisive battle happened.
