"You can't do this to me!" screamed one of the troublemaking sentient weapons, strapped into a chair in a pitch-black room, with only the illumination of a pair of red eyes floating on the background. "I'm supposed to be wielded by a chosen warrior of fate! Not used as a mere servant to you barbaric mongrels!"
"Oh really~?"
As such, these 'special' sentient weapons received a personal indoctrination and a little bit of psychological brainwashing from the best therapist of the kingdom. All of them became obedient and jolly but traumatized workers at the end of the day.
"How in the world are you able to traumatize a literal sentient weapon…" Vainya asked the ever-sadistically-smiling Archoseer of the Expedition Obscura beside her, who just happened to finish her session with one of the troublemakers, resulting in a happy and subservient sentient weapon exiting the therapy building.
