Butterfly, you are are *on it* girlfriend!
I noticed the illuminated chakras immediately when first looking at this deck. It was one of the many things that endeared it to me. It spoke in energy patterns I had already learned, that were easier for me to connect with and interpret.
Yes, many Fae cards have certain chakras illuminated. When I read, I often see which ones draw my attention the strongest, and why. This can be a very informative way of getting in deeper, intuitively, with your cards.
Sometimes, they just all are working. This is a different message. Perhaps to utilize all the different aspects of yourself in order to achieve what you're on the path towards.
It was the abundance of lit crown chakras that first led me towards a dialogue with my Fae about what all that stuff on their heads meant.
When I was sorting cards, early on, I sorted into piles of who had antlers or horns. Who had lit crowns. Who had flowers, and who had tree branches.
What did the groups of Fae have in common?
Meditating on that gave me the thoughts I shared about how they, being astral creatures, communicate/interact so strongly with us through the crown chakra level.
Some of us, in this life, wear flowers on our head. Weak, delicate but lovely connections. They blow in the astral breeze. The slightest hint of a message will dust off their crown chakra pollen.
Some wear antlers, or horns. These are like psychic antennae to the Faery, and act as lightning bolts of inspiration (divining rods of the Divine, if you will
(In antler people, when worn but unmanaged by a strong enough ego, these folks are prone to fits of anger and depression too. Their extreme natures seek balance only by swinging from one end to the other).
Some wear lit crowns of lights. Most blessed and pure. These are like psychic anemone to me, they float continually in the astral waters, picking up on every good spirit that happens by. When they are picked up, they light up. That's how I see that.
And then, there are the tree branches. Faery Godmother, the Sage (whose twigs, he assures me, are indeed branches at the opposite ends, funneling power in). These are the ones who have such incredibly strong links to the Divine, that they are indeed always of that world, no matter what their physical guise. They are creatures of infinite, even cruel, compassion. They are Faery guides of the highest order, (but different than Singers, whom I see as also High Fae, but pure energy forms, thought forms).
I hope some of this is helpful enough to continue a dialogue on the fae and chakras, because it combines 2 of my favorite subjects.
