If killed, Rondach will send Hired Thugs after them. Voada can also send out thugs if Ainethach of Karthwasten is killed, and vice versa. This is because the Creation Kit lists Voada and Rondach as Ainethach's children. However, there is no in-game dialogue or text that refers to their relation to Ainethach.
"Don't mind the dogs, they get anxious when they haven't had dinner."
- I have a delivery from Banning. "Oh, thank you. The dogs were getting restless. Here, this is for you."
- "Don't mind the dogs, they get anxious when they haven't had dinner."
- "It's been a hard day cleaning. Good, honest work I say."
- "You should talk to Anton if you need anything. He's the master chef."
Anton: "Voada, you spilled laundry water in the soup pot again! Do I need to cut off your fingers to teach you a lesson?"
Rondach: "You touch her and I swear it'll be your fingers that go missing, you stupid Breton!"
Anton: "What was that?"
Voada: "Now, now, brother, Rondach was just being his usual gloomy self, he didn't mean it, did you Rondach? You're just being silly again."
Anton: "Whatever. Just get back to work. Now."
Anton: "Filthy natives. Get to work. We have meals to prepare and no time to prepare them!"
Voada: "Right away, sir!"
Rondach: "Always another big meal to cook. Figures."
Anton: "Move it. Get to work. Get to work!"
