"Last Words of a Betrayer" is based in Guild Wars Factions campaign. The main character, Nesius Ry, has been banished from his clan for killing an executioner who was going to kill a young girl for stealing. As a part of the punishment, he must introduce himself as Nesius the Treasonist, and not share any relation with his clan.
As the story progresses, he finds that he is not only unable to let innocent die, but he cannot bring himself to kill those sickened by Shiro. So much so that he prevents one of his comrades from doing so. This calls the attention of the emperor. He is order to hone this compassion into a brutal killing force, or else be hunted down by all mercenaries in Cantha.
Tormented by the harsh reality set before him, Nesius now must choose. Kill or be killed. His world is closing in around him and he must fight to survive. But, will his morals conflict with the path that he will take?
