Santa Muerte was surprisingly clean and neat all of a sudden. With all the invaders to North America disposed of, her empire of ghastly beings created to drive them out, was no longer needed. She looked like a different person.
Unrelated to this an ancient witch with a "death" feel to her wanted to become incarnated to live physically in the world, and chose to sneak her way into the bosom of our well known vampire friend La Famida.
..or maybe one should say somewhat below the bosom. Timelines, dimensions and all that, vampires being not technically physical even if they are physical, makes it possible to twist things to one's advantage in unexpected way.
After all, our Earth is an astral dimension to the new, ascended 5D Earth, so who can really claim it has to be one way or another.
They even replaced Biden repeatedly and kidnapped Jeff Bezos, placing him in a different dimension while a reptilian took over his role, using their pet "shapeshifting" skill (actually just tricking all humans collectively by hacking the visual object link in the collective database - which is a shared construct of concepts for all humans linked to their subconscious).
So why can't an ancient death god then incarnate -partially of course- in a vampire bloodline? Vampires can't get pregnant. Yes they can, they just don't know how to activate their organs from lack of work on this part of themselves.
