"Ah. So you do know about the kingdom's history."
Kathos smiled, nostalgic. He remembered when his father had told him these stories of another time.
"In that case, you might know that not all the elbrethian forces fought in the civil war. While the majority of the army and the nobles chose their sides and battled - and died - seven men decided that it was time for them to leave the mirish coast. There was nothing more to gain in Elbreth, now that everything was falling apart. There was three generals, two great merchants, and two nobles. They lead an expedition to the south of the Storm Coast, seeking the riches of the Southern Lands. That is known history. What I'm about to tell you is... Well, the rest of the tale.
They arrived in the Emerald Bay, a great region south of the Green Empire. The region was inhabited by peaceful men that called themselves the Assai. The expedition took control of the bay - no tribal warrior could face the might of Elbrethian knights - and built seven great cities, creating the greatest nation ever seen south of the empire. Two generations, there was a... Misunderstanding between the seven lords, and the most powerful of the families wiped out the other six. Two men survived in the last family standing, and the one with the best claim became King of the Emerald bay, while the other one decided to return north, to the Storm Coast."
Kathos looked directly at John, once again smiling.
"I know my family's history well, John. My ancestor dealt with Kain more than once, and from what I can tell he was a magnificient bastard. I was surprised when I met William here, and even more surprised when I realized that Will might be even worse than his grandfather. I learned from the errors of old, John. I will not let one of William Vadud's best men running free in my city without anybody to watch him, if it's possible. Do you understand my position now?"
