Dwemer hands down, followed by the Ayleids.
well, i picked nords becasue they are racist, and commited genecide. those are the big reasons.
alyieds were the ones that first imprisoned man. then allysia did her thing
dummner are slavers
the dwemer are probably picked because they made the falmer blind then used them as slaves but i think that was a strategic plan. and it wasnt exactly forced. the falmer came to them for protection, so to prevent the falmer from betraying the dwemer the dwemer bvlinded them. the form they have now isnt from the dwemers actions. the dwemer blinded them but evolution really caused what happend to them. if you brought a stranger to your house wouldnt you be worried that the stranger would do something. that would leave you vulnerable to "harm"
