3 Some answers for the story

Why did the Chakaydaz family visited the king's city?

Well the king wanted to talk about the population of the Chakaydaz and it was because of how much people the Chakaydaz city has been having every year, and the kind wanted people to increase his populations and for trade he was gonna give them diamond armors for exchange so basically they were trading, but the terrorist got in the Kong's border not knowing they got inside the Kong's palace and killed him and the Chakaydaz saw it and were able to fight them off but they left without worrying of the King's death.

Well if u may ask why did the Chakaydaz wasn't worried of the king's death, well they already knew the terrorists was gonna come with the first glance of the terrorists coming in the border, and they didn't even protected him, because the king wanted the elite newborns from the Chakaydaz but he was gonna give it to the terrorists and they knew that too so they waited for the terrorists to come in the palace and left.
