As if the flat earth turtle wasn't insane enough as is, it turns out Kath is a member of some sort of vampire (their words not mine) or spiritual "energy" religion called House Quinotaur.
In other words, she believes in some mythical metaphysical dark magic. Something about Hindu chakras and upgrading them by sharing them.
In general you ideally want to create an energy loop between the vampire and donor.
The vampire take energy from the donor.
The vampire uses some of the energy or stores it, while allowing the rest to be taken back by the donor, after the vampire has cycled it through their own subtle body.
The donor takes a slightly lesser amount from the vampire.
The donor cycles the energy through their subtle body, refining it and making it more potent.
The vampire takes the new energy from the donor.
Back to step #2.
If you think of gasoline you have bronze, silver and gold. The vampire takes bronze energy from the donor. This energy becomes bronze-silver. The donor takes the bronze-silver energy and makes it pure silver. The vampire takes the silver energy and so on. It is a refining process on an energetic level.
Don't know if she's ever heard of the Law of Conservation of Mass, but who knows. It's magic bullshit anyway.
It doesn't look nefarious at all, but it's definitely weird, and combined with the rest of the context mentioned thus far it certainly calls her sanity into question.
Like many similar groups focused around metaphysical spirituality, they claim to be non-religious or optionally religious:
Non-Religious, we are working on developing a religious and also magickal path within our House. This Path however, is not necessary to follow to be part of House Quinotaur. We offer it as an extra for those who wish to explore themselves magickally or religiously.
Their beliefs fit the definition of a religion whether it's theistic or not, so this is just straight up false.
The weirdest thing I found was
this. Apparently some of their energy trading rituals involve giving blood (hence the term vampire being used). In the real, material world this can be dangerous. It seems like they're aware of this. There is a medical disclaimer before the page even loads when you click the link to it, however. Likely trying to avoid legal hassle.
Sources if needed:
https://archive.is/Qn7CVhttp://www.house-quinotaur.org/Wirla can provide additional backups if someone takes the pages down but I don't have reason to believe the group would do so, aside from it being strange.
The site itself mentions her somewhere but I couldn't be bothered to dig through it all. Their navigation bars don't appear to have a straight up members list available.
