Ancestral Magic

I was reading about how Vincent made Davina The gatekeeper to the Ancestral plane and i was wondering about what that meant. Like did she control who could use ancestral magic or was there something special about being the Gatekeeper. If you know something or have a suggestion please comment.

I don't understand two things Cleo said to Alaric.

1) What did she mean by "My grandmother's precious granddaughters."? Is it means that her sisters told her about her grandmother's death or what? I don't understand why she mentioned her sisters in this conversation.

2) The second thing is her grandmother's afterlife. If she went to "heaven" aka Bright World aka Found Peace, why did Cleo said she watches over her as ancestor? After all, that would indicate that her village was practicing ancestral magic and had their own Ancestral Plane. But if that's true, and she is an ancestor in their village Ancestral Plane, she couldn't see Cleo in Mystic Falls like Davina (when she was in New Orleans Ancestral Plane) couldn't see Kol outside New Orleans. Unless by the ancestor she meant the Spirits (spirits of witches) at Peace, then it would make sense that her village was practicing spirit magic.

Cleo: My grandmother's precious granddaughters.

Cleo: She at least was safe from Malivore.

Cleo: Having ascended into the heavens.

Cleo: I believe she still watches over me as ancestor.

Cleo: It was her power running through my veins that helped me infuse the artifact I inspired Leonardo to create with magic that could shield me from Malivore.

Why don't they create an ancestral plane in each country / city / state or even in the world at large like the one that existed in New Orleans? I mean, that wouldn't be much easier, besides, there would be more witches from the harvest to feed the ancestral plan without it dying. As witches didn’t need to channel their ancestors to use magic, or they wouldn’t even be limited to just one magic, since ancestors don’t seem to care if a witch uses black magic (well, Esther did and they never banished her for it or one punished).

I was wondering after someone from here informed me which expression fulfills wishes and that it serves the will of the person who handles this type of magic and can break laws of nature. do genies use this type of magic or not? they manage to fulfill desires without interfering with nature and laws, so is this the kind of magic they manipulate? I don't think it's a "weak" magic like traditional, spiritual or similar, as they have many rules. would anyone know how to give an opinion?

Am I right to assume with soul shredding that has been done in the past, that gives up the hope we will ever see the evil be taken out of a villian character, aka its shredded out of them?

Cause Id rather have that then straight out killing villians cause imo there is always something good and useful for the villian to counteract all the badness.
