Forgotten Tales

Hi I have a Daily Quest for the mercenaries guild. The quest is to kill 330 knights. I am fairly sure knights only Spawn at house of house in the main house, If you have not completed portions. All my alts are way past this point. So no I can't use an alt and dual log. Which is a lot of work. Is there another place I'm not aware of that spawns the knights? Thanks!

Knights should spawn inside any of the houses on the main floors.

Thank you!
