So you think a Holy Knight blew it up with a potential DF power or Uranus? I can't see Imu giving a Knight authority to use an ancient weapon, and if it's a DF power then it's way too OP for a side character lol
So now that these Holy Knights are getting a bit of an introduction I'm simply making assumptions that they may have been the ones to pull it off. These guys may very well be overpowered for all we know, or simply be blindly loyal enough to be allowed to drive an ancient weapon in the name of the Gorosei.
