They can't just conjure these women

After designing their maidens, although they were badass and could likely be added to the family, they realised that, should they take offence to being created under the assumption that they'd join this family and embrace their fabricated lives, they'd kill them in an instant or throw them into a rape dungeon as they make new chapters in their lives.

That's when the Family Maker chimed in, giving them the memorial spiel that a person is their memories, and the artefact is altering reality, so whether their birth is now or before, it doesn't matter. However, just in case this wasn't enough, it promised to add in a consent feature, ensuring that those made would be happy to have been made, even through the Family Maker. With that action, they hesitantly pressed the creation button, bringing Mabel and Xena to life.
