Even though the Sword Logic was false Oryx demands some respect for establishing himself as the better amongst his siblings and believing in it so strongly that he could believe that perhaps he wasn’t a part of the Final Shape and just a stepping stone for those who were. Ironically he managed to do what the Precursors failed to do. Savathûn has always been a character motivated by selfishness while Xivu has been overly emotional. Eris is more than the Hive persona.
