Because they formed within a Realm Space, they possess within them attributes of the Space Law. Also, because the world they are in haven't yet developed a world sentience, no one has stopped them from evolving, therefore having greater control of the law they received. Another thing was, the laws of this world aren't the only laws that was received by the Eternal Spirits; they also received the laws and powers that were used to create the worlds of the Diserian System, therefore, some of them has control over the power of Creation. Although not as powerful as the Origin, which came from Matthias' Primal Power within the Divine Siblings, it is still a significantly overpowered law to have.
It could be said that the Eternal Spirits of this realm began at a higher point than the rest of the normally formed Eternal Spirits.
