Very true, but I suppose they'll at the very least stay a while to do the things you said before returning and reporting back to Jok Lu (the High Saeng/High King of Da-Hyun).
And seeing as one of them is very ambitious indeed and doesn't have a wife nor children to return to, he might want to settle in the city more permanently. After all, since they will never sure how long it will be untill the next asassination in Da-Hyun, it won't be such a bad idea to stay away from those intrigues for a while.

But all of that will of course depend on the events that will take place in the future. 

Okay then! Glad to see I'm not the only one with a lack of experience on that field haha. I might ask you for help in the future Echo, but I'll try to do the best I can of course ;3
