Thinking back on what I did, I remembered that message of Hiacheius Dilechi about a Xacha sentenced to death. It was then that it stroke me: Why would the vigesimi court order someone to be killed? Of course it might be painful, however you do not *die*. You just go to the Death Realm, and although the Death Realm is (or is meant to be) a maze, it is not impossible to get out thus making the Death Sentence absolutely pointless.
Maybe that the Vigesimi court make the person drink a special potion, forbidding him from ever coming out of the death realm? Was the person sent to another place? Did the potion disrupt the transportation of the person, thus making it lost in another strange dimension? Those the vigesimi court have power to control who enters and leaves the Death Realm? I wonder...
Anyway, I hope that the Vigesimi court did not just do a huge mistake, because that would be really dumb from them.
