your offer is accepted however

However I have one condition to add,

that you show no further hostilities towards my former rival, the Kingdom of Boaam. One must defend ones nation, perhaps even make punitive expeditions to chastise a neighbor, but slaughter is not the way of kings. They have been defeated now, and further actions against them are no longer needed. Attempt peace with them, and I shall accept your offer with all gladness.

(cao cao, having been in the field, would have had only limited news of setrus's other actions of late, and doesnt know whether or not setrus intends further harm towards boaam)
