I have a multiverse theory

Ok, so I have a cc, tog, acotar theory. Am I crazy for seeing this? I'm sure a lot of other people have thought of this. Rhun dannan, ie, the tuatha de dannan. You have the dagda cauldron from the mythology, which can be the cauldron prythian worships, as well as the spear of lugh, which can be the king of hyberns spear, the Lia fáil stone, which can be the wyrd stones keys, and then since I can't spell for the life of me, there's also something called the sword of light (Claímh Solas), which can be the star sword. These are the four treasures of the tuatha de dannan. So the four objects of the tuatha de dannan line up with the objects in sjm verse. Although maybe the spear could be something further brought up? If this is obvious and something sjm has said, please don't attack me, because I don't watch her press tours and stuff.
