The third Oath is to swear oneself to a law or code, now nothing forbids this code from being changeable, but the Radiant themselves cannot change it.
The fourth Oath is to dedicate oneself to a task, nothing forbids that task from being to change a law, but nothing requires or even encourages it either.
The fifth Oath is to be the law, to live it so competely that the third oath is superseded., once again changing the law is not forbidden, but it isn't encouraged either.
I will remember those who are fogoten, who is more forgoten than the people at the bottom, the serf bound to the land he was born on, the slave subjected to the whims of another, kept there not by society, but by law.
I will listen to those who have been ignored, what better way to help them than to change the laws that ignore them
