We don't know for sure that the earrings were hemalurgic, I kind of regret mentioning that point, but they certainly could be. Perhaps hemalurgy existed in another form before the lord ruler's ascension. I don't think it says the koloss are of ruin, just that humans are and that they will use the koloss as their pawns to destroy eachother. I'm also now, like chaos questioning the mist spirit-preservation theory, however, i keep thinking if the mist spirit isn't preservation who or what is he/she/it? Someone opposed to freeing ruin for sure. Maybe Ruin and Preservation are stored in the well, and the mist spirit is a spirit of balance, or creation that put them there, it does say that the mists are both stability and chaos, right? Also, about that annotation saying there are only two beings, maybe Creation or Balance or whatever isn't a separate entity, but a combination of the two. That would ruin my other theory about the mist spirit thought. I don't think preservation would chose the msits to manifest itself in though, I think it would chose something that is solely of presrvation, which possibly lead me back to my other theory (boy I like contradiciting myself) that Ruin imprisoned Preservation in the changing mist, just as Preservation imprisoned Ruin in the power of creation, they used eachother's opposites to trap eachother. But that still doesn't work quite, because the mitss are still of preservation and ruin, but I guess creation isn't really of either. They used neutral forces to trap eachother, sorry if I confused, you, this was just my thinking on screen, I'll restate my prevailling hypothesis:
I think that there are two neutral forces that Ruin and Preservation can both manipulate: the mists which is of both of them, and the power of creation which is of niether really. I think that Ruin and Preservation trapped eachother- Ruin trapping Presrevation in the ever-changing mists, and Preservation trapping ruin within the power of creation that is in the well of ascension.
Thoughts??
