Yes. Yesterday and today, I discussed some theories with a friend.
The White Lady and who she is.
But let me start with the words from Greyroot in SilkSong. Those who have played and know how to get the witch's mark in HKSK (HKSS) know that Greyroot plants a parasite in us that eats Hornet's power and magic, and which we get rid of by partially taking away and subjugating what remains to ourselves and our will.
I thought for a long time about what Greyroot is and what its essence is, until a friend (another one) said that, according to the description, Greyroot resembles Cordyceps. A type of fungus that parasitizes insects, subjugating them to its will (usually ants, but that's not important).
So, the idea is that roots are a subspecies of Mushrooms (Mushrooms, as we know, do not belong to the plant class and are more animal than plant in nature, so living mushrooms surprise me less than living tree roots, for example).
Mushrooms such as Greyroot look for a host from which they can draw strength and energy and with the help of which they can grow and develop and/or continue their fungal lineage.
So, considering the information that Greyroot is most likely a parasite, and that it is similar to the White Lady in the very fact of being a root species
Why would anything prevent the White Lady from being the same kind of root parasite?
Simply, in the case of the White Lady, she was not seeking complete parasitism, but rather an alliance in which both parties could benefit.
The White Lady receives the power of the Pale King and grows fruit. And the Pale King uses the very fruits needed for his plan to create Vessels in which he would seal Radience.
This results in a mutually beneficial union.
Because the White Lady absorbs the power of the Pale King to create fruits from which vessels are made, they are in fact the “children” of both the White Lady and the Pale King.
They are just not very standard children in our understanding.
And also, regarding why the White Lady would seal herself off in order to no longer grow fruit (roughly speaking, to no longer reproduce)
1. Trauma associated with the vessels, because for her they were like children, and she does not want to repeat this again.
2. Conservation of the resources she had left from the Pale King.
Considering how much she could absorb of the Pale Kings power over time (not a lot at once, but little by little, where the power had time to accumulate quite well), she may feel like a real goddess.
And her children, who are made from her fruit, may have a good adaptation to the type of magic that can help them absorb any type of magic. This applies to the ending with Shade Lord, where the Ghost becomes a god by absorbing the power of Radiance. Most likely, this was influenced by the nature of the White Lady, whose body was made from her fruit, and the Void, which adapted the power of Radiance to itself, making it part of the power of the Void.
So, the verdict is as follows: the White Lady is like a root, a kind of Parasid-Cordyceps fungus that absorbs power for its life and development, but which lived in alliance with the Pale King for a mutually beneficial exchange of power for resources, or something like that.
