Different accounts assign different reasons for Meridia's appearance rather than remaining a hands-off observer with the other Magna-Ge, one book claims Meridia carried on an affair with one of the Divines and was cast out of Artherius for the scandal, other stories claim she left of her own accord, not content to simply watch or guide mortals but to physically move about in their world. However one of the Magna-Ge emerged from Artherius, onto the material world as a constant, Meridia. Most Magna-Ge remain as unseen guardians existing on the edge of Aetherius, the realm of magic, and Nirn, the mortal world, Atherius is very much the games' in-universe equivalent of heaven. There were those among the et'Ada that could not bare to leave creation and so instead choose to give up the scope of eternity to stay behind and watch over the cosmos, such beings are called Magna-Ge, 'Children of Magnus'. The sun was the patch of sky torn away when Magnus himself left.

Magnus and the other et'Ada, choose to leave creation rather than be tethered to it and watch as it's eternity eventually withered away, and so they left, tearing holes in the sky as they went, these holes are said to be the stars in the skies. Magnus was however burdened by the concept of reality, for he had put such effort into it that he could not bare to see it end, which he knew it would as the laws he had to establish upon reality dictated that all things must end.

Magnus was the architect of reality and through his work the cosmos was reshaped to a place of physical laws but boundless potential. Lorkhan's head et'Ada was the god of magic, Magnus. Lorkhan charged his creations the et'Ada with the task of creation of the mortal realms and perceptible reality. Originally in the time before Daedra were Princes, before the Nine Divines came into being, and it is said before time was time, There existed the God Lorkhan.
