Dark Star Aurelion Sol

So the Dark Star is this powerful corrupting influence from the cosmos, and Sol is the Star Forger. Well what if the Dark Star was his mistake? Sol also maintains the stars, could the Dark Star be an effect from the lack of maintenance? And as time went on the Dark Star grew into something else Sol didn't expect.

I just think it could end up fitting into Sol's lore really well, and it'd be cool to see. I think Sol and Karthus would be pretty good additions to the skin line imo
