The Kurk Clan remained peaceful for the next six years after the expedition to the Special Realm.
At that time, Kermu reported everything to his grandfather, including how Kreg and his group had tried to kill him and how Yale remained behind to help them to escape.

The Zhan Clan and the Kurk Clan always possessed a good relationship, but in the last years with the growth of the power of the radical faction that opposed to Serka's faction, the relationship between the two noble clans had deteriorated a lot.
