I am usually not this "New Age" but both starseeds and the Pleaides have shown up for me in synchronicities lately.
I have been watching a bunch of videos and things on the topic, but I think most new-agers are full of shit so I had to find out for myself.
Here, I look at Pleiadean spirits on Earth. The first question is really "Are there Pleaidean (starseed) spirits on Earth?"
It looks like the Pleiadean spirit on Earth is a thing. It looks like they are emotional stabilizers for the people around them, and they like to be productive. Maybe they live best when they have a workshop.
The reversed Ace of Swords shows that these spirits might not be here by choice. This is also true in the reading of the straight up Pleiadean aliens. So just like the pure aliens, the humans with alien spirits were ordered to be here.
The Page of Pentacles shows that it's important for these people to keep learning and to remain curious.
The Magician and The Devil here are so interesting, because it looks like someone made a great boast, and is now trying to back it up.
The message to give to Pleiadean spirits is not to give up, and try to let go of hate and war energy. To ascend through the portal, you have to get past the trolls. If trolls make you mad, you will never ascend.
As far as identification, the 4 of Wands says there might be identifying marks on the hand or wrist, as well as some kind of a feeling of commitment to the Pleiades. It will be interesting to see if I can find people with a clear pentagon on their hands...
Live long and prosper, Hive.
