Zarjab begins to outline the ways of the Maltites.
The social aspects are ones you can somewhat agree with and may have seen in other cultures. While Malteen himself comes first, his followers come second and everything done by the Maltites is done in hopes of bettering their stance and situation. Everyone learns to fight to protect their people. Their morals are built on this.
However, those who go against the will of Malteen or stop benefitting the Maltites are branded heretical and executed. He implies that your first act of loyalty to Malteen will be to serve as executioners to imprisoned heretics and join in the Feast that follows.
