Arakki being the capitol of Sol is a wise move I’m more referring to the Regent thing. I know about Nova being Earth’s representative to the galactic council and I wouldn’t be surprised if Earth’s world governments knew about that and accepted it not because he is human, but because of his experience. Though Krakoa claiming they can speak for him without getting his consent as of know is yet to be seen, but should they have not talked to him or others about who can speak for all of Sol on his or others behalf is wrong and filled with hubris.
