Comments of chapter undefined of Dragonborn Saga

So today I was playing Dawnguard DLC for my Skyrim and you know this novel has forced me to look at things in a very Broad View and when I was thinking about it. Curious thought struck me blinding the eye of the dragon and causing Eternal Night that sounds like a simple plan but even Harkins not that big of an idiot to not know the consequences of what would happen but then another thought struck me Serrano's blood is basically painted by Molag Bal an extension of his divinity a part of himself his essence This train of thought led me to my Theory and it makes a lot of sense if you think about it well relative to this story at least so I was thinking back on how Azura's Star was corrupted and how this cause mannimarco influence to rise now I know that was simply because he was feeding on an avatar of her but still when one Falls someone else's influence can rise Let's say that seranas origin blood was used to Blind the Sun and cause Eternal night my theory is that Molag Bal being the Lord of domination would gain absolute authority over creation Now this might sound far-fetched but let me explain there are three deities that are known to have direct ties to the Sun akatosh Magnus and Meridia what would happen if one of the daughters of coldharbour blood where to taint the Sun It's just a theory but Molag Bal would in all likelihood gain Dominion over the three deitys and its  aspects, control over time control over all Magicka and then control over infinite energies Molag Bal would  basically turn into an omnipotent deity within reality having control over all three aspects now you would be able to oppose him because he would literally have unlimited power unlimited control over time hand unlimited control over Magicka Basically if the blood of a daughter of coldharbour touches the sun that's it reality would be over because Molag Bal would reign supreme over all creation that's just my theory and thoughts on it I was just going off of lore that was already established throughout the novel and it actually terrified me when I came up with it
