Aron had some knowledge but much of it was on misleading or incomplete information on how the bonds work. The more he went through with he line of thought there were more inconsistencies with the bond. It was quite difficult to remove it and even more so to make a new master for an existing slave whilst the old one lives and does not permit it. He was not however mistaken with how effective these brands were in preventing escape and promoting obedience in any unfortunate with the slaves brand. The simplest way and one that he knows definitely does work is to kill the existing masters. Historical books did show that formal challenges could settle a dispute over a right of a slave ownership. Because Tal'both had a strong conviction in the strong have the right to rule the weak, it only stood to reason that the masters mark went to the strongest.
