OK so I have a question about this. If a person holding Ishar's honor blade is a false bondsmith due to the absence of a nahel bond, then was Ishar a false bondsmith? I can't remember for sure if Ishar was actually involved in the creation of the oathpact, but if he was then it seems that his blade is what gave him the power to do so and following that line of reasoning, whoever holds his blade should be able to undo it? Am I missing something?
