Rachel Duncan: proclone or as she calls herself, "self-aware". You don't want to mess with Rachel, as she won't stand for it. But as the seasons go by, you discover the human behind the monster.
The cache takes you by her apartment building, One King Street West Hotel & Residence. In Rachel's image, this cache will be tricky to get your hands on and will require shady tactics. High muggle times definitely will require stealth skills. But when you find it, you will surely enjoy the reference to Rachel's dramatic loss of power.
