It was also going to be something to give my character a drive to do something other than just learning magic but means to get more godstone and ways to mend the sword. He doesn't want to have a broken prison as a weapon where the prisoner is trying to kill him at a daily basis. Not to mention tormenting him through nights via visions of a giant snake devouring the world. And then there is the weight that it's the character´s responsibility to carry the sword due to family sense of honor and what not.
